Apples

Treasured Red Columnar Apple

An exciting "New" hardy columnar apple tree - an introduction from the University of Saskatchewan! Super compact with maximum yield! Instead of developing horizontal branches as standard apple trees do, these trees form fruit on short spurs that develop along the main trunk. Tree width is only 1 to 1.2 m (3 to 4 ft)! Mature height is 4 m (15 ft).

The fruit is bright cherry red, large, and smooth with a nice waxy bloom. Fruit ripens in Mid-September with an excellent texture and flavor similar to a McIntosh apple, and stores well!

They fit easily into the smallest gardens; you can plant several along a fence or deck. Plant Breeders Rights applied for. 2018 saw us plant trials for the University of Saskatchewan.

Prairie Sensation Apple

Released by: Rick Sawatzky, the University of Saskatchewan in 2008. The fruit is large, between 7.3 and 8.6 cms in diameter (average of 10 fruit is 7.63 cms or 3 inches) and roundish to slightly oblate in shape. The flesh color is white, and the texture is fine, firm, tender (breaking), crisp and juicy. The core size is medium to small and sets as singles or pairs and requires little thinning.

The tree is slightly leggy with an open crown but sets up a moderate number of short spurs. It is not a tip-bearer. It is hardy and continues crop after crop in spite of some tough years. Prairie Sensation has been fully hardy. The fruit stores well, consistently receiving good sensory evaluation scores in January and February.

Some apple experts in Alberta rate this as the best apple for our area; I know we sure think it is exceptional.

Prairie Sensation


Bernie Nicholai, the Edmonton area Pear expert: Brand new Russian pears are proving hardy in the Edmonton rural area. These are generally F4 crosses that have taken decades to produce. The Canadian hardy pears are all F1 crosses with Siberian pear, which generally only produces a very tart, almost inedible fruit. The Russians have found you need at least an F3 cross to get the size, quality, and hardiness, but this takes decades of breeding, and nobody in North America had the time or interest to attempt this.” There are more pears coming from this program. Keep posted!

Pears

Delicious Pears

At long last, we are getting varieties that produce good fruit. Pear trees are 15 to 20 feet tall and are covered in fragrant white blooms, making them a beautiful ornamental (please note that cross-pollination is required for these trees.) 

Check our estore for varieties.  

Krazulya Pear

Evans Edible Mountain Ash

Discovered in Calgary by Dr. Evans. This is a very columnar tree with dark green foliage about 15-20 feet tall. Heavy producing, large orange clusters of fruit have a sharp, sweet flavor. This mountain ash makes excellent jams and jellies. Normal mountain ash is bitter and bad tasting. Fruit appears on 3 or 4-year-old wood. Zone 2.


Plums

Plums Grown to Perfection

We carry both Asian (Prunus salicina) and Canadian (Prunus nigra) plums, as well as hybrid crosses between the two. The key to plum production is pollination, and DNA Gardens has perfected the process. Learn more about the plums that we carry below.

 Plum Type Hardiness Zone: Plum Fruit Usage Season of Fruit
H - Hybrid Z0: Below -50°C E - Eating Early
A - Asiatic Z1: -50°C to -45°C C - Cooking & Canning Mid

More About Our Fabulous Plums

We graft a lot!  Some trees we bring in.  Grafting allows us the ability to carry the newest and greatest types of fruit. We may not carry everything, but we do carry quality.  All of our plums are dead rock hardy; however, the pollination can be a bit tricky.   The following plants are available on our tree lot:

Fofonoff Plum (Asiatic Plum, Early-Mid Season)
Sometimes called Homesteader, the skin of this plum is lime green with a red overlay. It is firm, juicy, and very sweet. The Fofonoff plum tree is a must for cold climates as it is hardy to Zone 2 and produces a wonderful sweet plum. The original Fofonoff plum tree was selected by Wasal Fofonoff in Buchanan, Saskatchewan, in 1973.

Patterson Pride Plum (Hybrid Plum, Late Season)
An incredible plum for prairies, this fruit has a brilliant red skin with a bright, golden flesh. The tree is of excellent quality and is a heavy producer with a unique weeping form. This is a hybrid plum and requires a wild plum to have fruit. Its fruit is large — 4.5 centimeters and slightly flattened. It matures late in mid-September (the latest to ripen of the plums), is sweet and juicy, and excellent for eating fresh. It is also very good for freezing and making jam, good for jelly and canning, fair for pie. It's hardy to Zone 2. This tree was developed at the University of Saskatchewan and was released in 1960.

Brookgold Plum — Prunus salicina 'Brookgold' (Asiatic Plum, Early Season)
2.5 to 3 centimeters around, this fruit matures first of the plums in mid-August and has yellow flesh. It is juicy and very sweet and is a free-stone with bright gold skin that has an orange blush. Those that taste it want more, as it is excellent for fresh eating. It is, however, poor for canning and jam. Plant them with other Asian plums, such as Ivanovka or Fofonoff. They are hardy to zone 2A and were introduced by Alberta Horticulture Research Centre, Brooks, Alberta, in 1979. This is a great early plum for fresh eating.

Ivanovka Plum — Prunus salicina (Asiatic Plum, Early Season)
With a thin, yellow skin overlaid with red, this semi-freestone plum has orange or pink flesh and is firm, juicy, sweet, and aromatic. It's excellent for fresh eating and very good for canning, jams, and pies. Plant them with other Asian plums such as Brookgold or Fofonoff for pollination. These plants are hardy to zone 2A. They were introduced by Agriculture Canada out of Morden, Manitoba, in 1939; and are one of the standards by which large, hardy plums are measured.

Lee Red Plum (Hybrid Plum, Early Season)
One of the best red early red plums around for our climate, according to Dr. Evans, they were developed by Mr. Lloyd Lee of Barr Head Alberta.

Plums On a Tree

Pembina Plum — Prunus nigra x P. salicina 'Pembina' (Hybrid Plum)
Among the best of the large dessert plums, this fruit is about 5 centimeters (2 inches) features dark-red, thick, sour, and astringent skin, and its flesh is orange-gold and is soft, juicy, and sweet. It's very good for fresh eating and fair for jam. It matures in late August and early September. Hearty to zone 2, its tree is upright, spreading, and vase-shaped; and has been one of the prairie standards since the late 1920s.

Pure Wild Plum
These showy plants have yellow or red fruit. They can be very hard to find as they are considered "critical" trees. This is because the plums have been pollinated by other wild plums, not by hybrid plums, making them the best pollinators for hybrids. Perhaps get a neighbor to plant complementary plants as bees know no boundaries.

Tip: Pin their branches close to the ground so both early-blooming and late-blooming hybrids will be pollinated. If space is a consideration, try planting them about 2 feet apart, pining to prevent over-crowding.

Black Currant Plants for Commercial Growers & Market Gardeners

DNA Gardens sells rooted plants of black currant on a contract basis. We require a year to strike cuttings, grow, overwinter, and rooted plugs for the following spring. Call us for a quote and to discuss timelines.

  • Ben Alder
  • Ben Sarek
  • Ben Connan
  • Ben Tirran
  • Ben Hope
  • Ben Nevis

Ben Nevis Black Currant

Known for heavy, commercial production, Ben Nevis is a sister seedling of Ben Lomond, with large, firm berries by mid-season. It has good frost tolerance and has fruited well in the Edmonton region with no signs of over-wintering problems. This currant variety comes from the Scottish Crop Research Institute (SCRI) and is made to resist rust, grow vigorously, and yield great production.

Ben Hope Black Currant (New)

This is a popular commercial black currant in England that is known for its winter hardiness. Its upright growth is rapid, and the plant can become quite tall for an ideal harvest. The majority of the fruiting plant is within the "strike zone," making the fruit more likely to be harvested mechanically.

Ben Alder Black Currant

This is another Scottish currant with high yields of medium-to-small berries, which we harvest by machine. These berries produce a juice with high color stability, making it a top choice for juice extraction. They also flower late, escaping Spring frosts, while remaining more resistant to mildew than Ben Lomond currants. Ben Alders are susceptible to White Pine Blister Rust (WPBR), but this rarely affects production, as the rust is usually only bothersome late in the season.

Ben Sarek Black Currant

This is a mid-season cultivar that produces large, firm berries. It is very productive and displays a compact, semi-dwarf growth habit. It grows about one meter tall and is ideal for PYO farms and home gardens. Ben Sarek also fruits ahead of Ben Lomond and is resistant to mildew and WPBR.

Ben Connan Black Currant

Ben Connan is a new black currant variety bred by the Scottish Crop Research Institute and is a cross between a Ben Sarek and Ben Lomond. Its large, dark blackberries have a high yield and a compact growth habit, suitable for mechanical fruit harvesting. In the UK, Ben Connan crops are harvested approximately four or five days earlier than Ben Lomond and boast a more uniformed, even ripening. It was also the highest yielding variety in the UK National Trials. Though not ideally suited for juice production, it is excellent for canning, jams, preserves, conserves, and consuming fresh. Let them ripen though — North American palettes require this fruit to be very ripe. Dare to compare:

 Measurement Ben Connan Ben Lomond
Berries per 250g 187 206
Ascorbic Acid Content per 100g 130 mg 119 mg
Pounds per Acre 16,684 14,810

Come to the farm and sample the fruit!  Most fruit trees we list here are fruiting well somewhere on our farm. We  graft and grow a lot of our own trees, and it allows us to offer items not necessarily sold elsewhere. Unique! That is the word!


Our Cherry Orchard

Evans Cherry — Prunus cerasus
Dr. Evans discovered this incredible cherry and knocked himself out, sharing it with the world! DNA Gardens helped the process, and the cherry has been selling non-stop since 1995. We were the hub for nursery sales, and when folks witness a tree laden with fruit, it becomes a must-have. First overlooked for years, these cherries have been growing since 1923 in the Edmonton area. These cherries are extremely hardy and withstand -45 degrees Celsius regularly. In unofficial comparisons in Edmonton, Evans out-produces Meteor, Northstar, and other contenders by 5 or 10 to 1 margin. Mature height of 12 to 14 ft. The fruit is a bright red cherry with translucent flesh. Ripe in late July when it pulls easily from the stem, fruit can be left on the tree well into September. In fact, the flavor mellows and sweetens with time. The flavor is bold - a mixture of sweet tartness. Healthy Too! Per 1/2 cup: 25% of daily Vitamin A requirement. (Six times more than sweet cherries) and only 39 calories. Excellent for eating fresh, good for canning and pies are great. Because it is self-pollinating, you only require one plant to set fruit. Yields of 50 pounds per tree are easily attained!! It produces in 4th year. This plant is hardy to zone 2A, not 2B - zone 3 preferred. Plant in rows 18 feet apart with 8 feet between plants in the row. Kirsch liquor is made from sour cherries. The strong cherry flavor stands up well to processing, and these cherries are often used for pie filling, jams, and jellies.

Rose Cherry — Prunus cerasus
The Rose cherry is an early maturing shrub, loaded with dark-skinned, tart cherries. It will be a small tree in more protected locations. It fruits as early as 2-3 years. Large fruit - 5-7 grams. Great for bonsai. Dark brown skin with red flesh. (Evans has yellow flesh) The rose can be grown as a tree or a shrub. It produces fruit consistently at DNA Gardens in central Alberta. This cherry is also known as Lutowka, and it was originally imported into Alberta by Kris Pruski from Warsaw, Poland, in 1988.

SK Carmine Jewel
Favorite of DNA Gardens! We think of this plant as a little princess - well behaved and beautiful.  Combinations of P. cerasus and P. fruiticosa (Sour cherry and Mongolian cherry) Introduction from the Department of Horticulture Science, University of Saskatchewan. Skin and flesh is dark red. The fruit is about 4 gm with a small round, hard pit. (desirable when using cherry pitting machines or pressing fruit for juice). High flesh to pit ratio. Superior cold hardiness! Self-fruitful, in other words, cross-pollination is not required.

The fruit is exceptional for pies, cooking, juice, wine, or flavoring for ice cream or yogurt. Many like to eat the cherries fresh, especially towards the end of the season when the tartness mellows! SK is juicier than sweet cherries and has similar sugar levels, but additional citric acid makes them tarter. Near the end of the season, fruit can be collected quickly by shaking tree limbs and using a tarp. The season runs from mid-July till the first or second week in August. It has great potential for landscaping in small yards.  With glossy leaves and crisp white blooms - train to either a shrub or small tree. Plant a flowering and fruiting hedge.  Plant height is 6 to 8 ft (2 m) and has a very low tendency to sucker. 

SK Carmine Jewel is one of six new and exciting cherries released from the University. Carmine Jewel will always stand out for its earliness. Its value will remain because its fruit will command top dollar early in the season. As more information is coming in, it appears that Carmine Jewel will be the workhorse of a new cherry industry. It pits mechanically very well, and the fruit makes an incredible pie, and the juice has a very good flavor. This is a winner that is not going to disappear!

University of Saskatchewan Cherries — Prunus cerasus SK Tart Cherries
At long last, what we all have been waiting for - prairie cherries! Zone 2, hardy.

The University of Saskatchewan has released their incredible cherries, the result of breeding work since 1940. These cherries have been tested extensively for the last ten years in Saskatoon, Saskatchewan. They are grown without irrigation after establishment, in heavy clay soil with a pH of 8.

The U of S cherries are bush fruit with dwarf stature - a mature height of about 8 feet tall, unlike eastern tart cherries that are 15-25 feet tall. The shrub-like habit makes it suitable for over the row harvesters, the kind used for saskatoons. All of these selections are suitable for high-density plantings, which would be a strong competitive advantage.

Another very significant advantage of producing sour cherries on the prairies is the reduced incidence of pest problems. Growers in Ontario or Michigan require from eight to sixteen or more spray applications to control a variety of diseases and insect pests. Experience at the University of Saskatchewan suggests that no more than one of two applications would be needed to control cherry fruit flies and leafrollers. These cherries are good candidates for organic production.

The five varieties plus SK Carmine Jewel, offer 6 to 8 weeks fresh fruit consumption because of early and late varieties. Fruit holds well on the bush – doesn’t drop. It will wait while getting sweeter and sweeter. When very ripe, just give the branches about five shakes to remove all the fruit. Harvest a tree in just a few minutes. If the fruit is holding on, try again in a few days. High yielding! Mature trees produce from 10 to 15 kilos of fruit per bush. Size of quarters! Dark red fruit is high in sugar. As much or more sugar than Bing cherries! Plants are self-fertile, and one can expect the first harvest within three years of planting.

If you are a commercial grower, give yourself a marketing edge by being the first in your area to grow cherries!

Crimson Passion
This is an exciting one!  Excellent fresh eating cherry.  No suckers!  Fruit size is large at 5.8 grams per fruit.  Highest sugar content – up to 22 Brix.

Cupid
Most years, this is the largest of all the cherries weighing in at 6 to 7 grams! Good flavor for fresh eating with a hint of astringency. Blooms 1 week later than the other cherries.
Cupid

 
Juliette
A fresh eating type. The University affectionately calls it "Sweetie." Large fruit at 4.5 grams with Brix up to 20. Few suckers.

Romeo
This is a dark red/black cherry similar to Carmine Jewel's appearance but ripens later. Very flavorful. Good for fresh eating and processing. This productive cherry is one of the best for juice.

Valentine
This is the most productive of the selections. It is looking very strong with a much heavier flower bud load compared to the other cherries. It fruits heavier and fruits at a younger age. Slight suckering. The fruit size is about 4.5 grams.


Bors Released on the 100th anniversary of Horticulture at the University of Saskatchewan  7 new cherries. Here they are

4 Cherry Musketeers

The rest of the story: 4 cherry Musketeers!  Where on earth do these names come from?  Well here you have it.

The true story of the 'three' Musketeers who were based on four high-ranking French soldiers of Louis XIII elite Black Musketeer regiment. The Three Musketeers, first published in serial form in France in 1844, is a classic. It has been translated into many languages, repeatedly filmed, and its heroes - D'Artagnan, Porthos, Aramis and Athos - have become literary icons.

Yet, outside France, few people are aware that all four are based on actual historical figures:  Armand de Sillegue; Isaac de Portau; Henri d'Aramitz; and Charles de Batz.   All four came from Gascony, and all four were members of the elite Black Musketeer regiment during the 1640s. The Four Musketeers gives an account of the historical background of the real four musketeers, who came to Paris in the 1640s and thus witnessed some of the most dramatic moments of seventeenth century France: the last years of Louis XIII and the struggle for control over him between the scandalous royal favourite, Cinq-Mars and the dying Cardinal Richelieu; and the rise to power of Cardinal Mazarin.
(source: Nielsen Book Data) Why is it called 3 Musketeers when there are 4? 

The three Musketeers from the book are Aramis, Porthos, and Athos, three close friends and exceptional Musketeers known as the Inseparables. ... And since D'Artagnan's goal throughout the novel is to become a Musketeer, if the author, Dumas had entitled the novel The Four Musketeers, that would have given the story away, wouldn't it?


D'Artagnan Cherry the 4th Musketeer 

Dr. Bors  bred cherries for commercial growers for dependability, flavour, and ease of harvest. It’s shorter than the Romance series (having some of the same parentage as Juliet, Valentine and Crimson Passion) topping out at about 6’ in height when fully mature. It has burgundy coloured fruit with flavour similar to Valentine and Juliet. Most years it ripens in early August in Saskatoon.
 
In recent years, commercial growers have been using special sideways harvesting machines to harvest cherries. The shorter stature and limber, arching branches of D’Artagnan are well suited to sideways harvesters which bends the branches over a conveyor belt. The fruit only drops a few inches versus several feet with conventional harvesting machines, resulting in far less damage to fruit. D’Artagnan also requires far less pruning than other varieties, which reduces labour costs for growers.
 
Although Dr. Bors developed D’Artagnan with commercial growers in mind, this sour cherry is well suited to home gardeners who want a hedge of cherries. To form a hedge, plant them one metre apart in a row about one metre wide. Mulch the area so there is no grass or weed competition. For the first few years the plants will be individuals. When suckers begin to appear between the plants, don’t remove them, just let them grow up to fill in the rows.
 
Why the name D’Artagnan? D’Artagnan was the fourth musketeer in the tale of “The Three Musketeers”. This is the fourth variety of Dr. Bors’ “Musketeer” series released in Europe.

Porthos Cherry Musketeer

Varieties used for comparison: 'Carmine Jewel' and 'Juliet'

Summary: The plant growth habit of 'Porthos' is semi-upright whereas that of 'Carmine Jewel' is spreading and that of 'Juliet' is drooping. The leaf blade of 'Porthos' is shorter than that of 'Juliet'. The nectaries of 'Porthos' are greenish yellow and positioned both at the base of the leaf blade and on petiole whereas those of the reference varieties are orange yellow and predominantly at the base of the leaf blade. The fruit of 'Porthos' is large whereas it is small for 'Carmine Jewel' and medium sized for 'Juliet'. The shape of the fruit of 'Porthos' in ventral view is oblate whereas it is circular for 'Carmine Jewel' and reniform for 'Juliet'. The fruit skin of 'Porthos' is medium red whereas it is blackish on 'Carmine Jewel' and dark red on 'Juliet'. The shape of the stone of 'Porthos' in ventral view is circular whereas it is broad elliptic for the reference varieties. 'Porthos' begins ripening mid-season whereas 'Carmine Jewel' begins ripening very early.

Description:
PLANT: semi upright habit, grown on own roots, weak vigour, medium branching, buds distributed along entire branch, begins flowering and fruit ripening mid-season

‘Sweet Thing’ Sour Cherry, New for 2021 By Bob Bors Released on the 100th anniversary of Horticulture at the University of Saskatchewan
History ‘Sweet Thing’, a hybrid of ‘Carmine Jewel’ and ‘Erdi Jubileum’, is the highest quality sour cherry we have observed in our cherry breeding program. ‘Carmine Jewel’, the first sour cherry variety we released, has been dependable over many years. ‘Erdi Jubileum’, from Hungary, has great fruit quality but is not hardy enough for growing in the colder areas of the Prairies. Also known as ‘Jubileum’ ®, it was Rick Sawatzky’s favourite tasting cherry among those he was growing in pots in the greenhouse and using for breeding. The breeder in charge of the Hungarian cherry program indicated that ‘Jubileum’ ® might have sweet cherry in its lineage due to open pollination. Although still experimental in zone 3 (which is Saskatoon’s hardiness zone), we think it is suitable for hardiness zone 4 or warmer. In Zone 3 it may do well in protected areas such as urban backyards or rural areas with windbreaks, but additional testing is still needed. About 2010, when temperatures dropped to -50°C, ‘Sweet Thing’ suffered severe dieback and did not recover because it was already in a stressed situation. Apple trees were crowding it on the west side and within the row most of the other cherries were taller. Fortunately, we had sent cuttings of it for virus- free clean-up to an Agriculture Canada facility in British Columbia. These are now certified virus-free and we are beginning to test it in warmer areas of Canada and are also establishing a new trial at the University of Saskatchewan.

Description:  While most of the University of Saskatchewan cherries are 3 to 4 grams, ‘Sweet Thing’ has large burgundy fruits in the range of 5 to 6 grams. They are sweeter and firmer than most sour cherries. The bush is expected to grow to about 2.5 meters, but needs additional testing in more areas. The original plant was a heavy producer when only 1.5 meters tall.

‘Cutie Pie’ Sour Cherry, New for 2021 By Bob Bors Released on the 100th anniversary of Horticulture at the University of Saskatchewan

History:  ‘Cutie Pie’ is a grandchild of Les Kerr’s secret breeding program. Sometime in the 1940s while working for the federal government in Manitoba, Les Kerr began interbreeding Mongolian sour cherries (Prunus fruticosa) and European Sour cherries (Prunus cerasus). When he became head of the Forestry Farm Shelterbelt Centre in Saskatoon (part of the federal government) he was supposed to be breeding only shelterbelt plants. But he never gave up on his goal to create hardy sour cherries for the Prairie. He continued making crosses among superior plants but all the plants were planted at various friends farms to avoid the scrutiny of his Ottawa superiors. In total he worked about 40 years on this project! During the last few weeks of his life when he was hospitalized, he sought the advice of George Krahn of Lakeshore nursery about what to do with his hidden treasures. George convinced him to donate the collection to the University of Saskatchewan breeding program which at the time was under the direction of Dr. Cecil Stushnoff with Rick Sawatzky as the head technician. Les informed them which farms to visit to see his best cherries. Stushnoff and Sawatzky visited the best farms gathering fruit for seeds and cuttings which were then grown at both the University of Saskatchewan and Lakeshore nursery. When those seedlings grew up, Rick Sawatzky scrutinized the Lakeshore collection and gathered seeds for the next generation to be grown at the University. ‘Cutie Pie’ resulted in the next generation. It was selected for being unusually dwarf, sweet, and having bright red cherries. Having personally tasted a few hundred Mongolian European hybrids at one of our former testing spots, I can attest that most are extremely sour and Cutie Pie is the best tasting of that type.

(‘Big Red’ Sour Cherry  NOT WOWZA  - BIG RED)
By Bob Bors This variety is currently being marketed in the USA as ‘Wowza®’. Fifteen years ago, an American company visited us several times and took back several selections to test. After testing they decided that ‘Big Red’ was what they wanted to market first, but they didn’t like that name so they changed it, with our permission to ‘Wowza®’. I recall ‘Big Red’ had unusually large red cherries that were 50% longer than wide with small lobes on the bottom. It looked like a miniature red delicious apple. I’d never seen any cherry that looked like that. It tasted good, didn’t seem to have winterkill, but wasn’t as productive as the other varieties. One thing I’ve wondered about is if the lower productive varieties are hardier. ‘Big Red’ should be considered highly experimental. The field that ‘Big Red’ was growing in was renovated and in the original plant was destroyed. My fault, I forgot to tell the crew to save it is, so we haven’t seen it in more than decade. I really wanted to breed with it because that shape is so unusual. When the American I’d asked one of our tissue culture propagators to make us about 30 plants so we could grow it again. But wires got crossed and the propagator made about 300 plants instead.

  • Tart cherries with vivid, red color
  • Large fruits with excellent flesh-to-pit ratio
  • Yields up to 20 lbs. of fruits
  • Manageable, 5-8 ft. tall plants
  • Hardy to -40 degrees F

Picking is easy, and the fruits are huge with our newest bush cherry tree. Naturally dwarfed, Not Wowza! produces plenty of tart, red cherries that cook up beautifully in pies and desserts—no dyes needed!

Huge cherries! Fruits grow up to twice the size of our popular Carmine Jewel cherries. They have an excellent flesh-to-pit ratio, so you'll have plenty to enjoy. Each plant yields up to 20 lbs.

Manageable plants! Not Wowza! grows 5-8 ft. tall—so netting, pruning and harvesting can often be done while standing on the ground. Plus, it can be grown in patio containers.

Cold hardy! Developed at the University of Saskatchewan, Not Wowza! handles the cold and is a great choice for Northern growers. Grows in zones 2-7.

Our Saskatoon Orchard  

We have over 19 different varieties of saskatoons in our test orchard!  DNA Gardens has fancy, large-fruited saskatoons that are so desirable. We plant the best-being tissue culture where a Martin is a Martin, Honeywood is a Honeywood, and a Theissen is a Theissen. You get the idea. The best picking!

Honeywood
Good fruit size at 16 mm with full and tangy flavor. Flowers 4 - 8 days later than most other varieties and also ripens later. We like the vase shape habit of growth and the low suckering. Very productive and consistent yielding. The bush size of 8 ft keeps it in harvesting height. (25 cent royalty)

Northline
Larger fruit than Smoky but smaller than Martin and Honeywood. Good flavor. Shorter shrub than the other three toons listed here.

Lee #3
This variety was selected by the late Mr. Lloyd Lee. On our farm, we really like it. It ripens ahead of the other saskatoons, and it extends our season. 5 to 6 feet tall, with excellent flavor. The fruit is the same size as Northline. A real winner.

Lee #8
Again, a variety that few grow. This is one of Mr. Lloyd Lee's. The parentage, Northline mother, crossed with a Theissen father, created a high-quality saskatoon that yields well, has good fruit size, and excellent flavor. This one is similar to Northline, but it ripens more evenly. About 6 to 7 feet tall, but this always depends on the amount of moisture.

Martin
This is a selection of Theissen made by D. Martin of Martin Nursery in Langham, Saskatchewan. The average berry size is larger than Theissen, and it ripens more evenly. This is a great berry for U-PIK. People are drawn to this berry because of the great fruit size.

Smoky
This is the Saskatoon everybody knows. The fruit is large, round, and sweet. Smoky has the highest sugar/acid ratio of today's varieties. Habit is upright and spreading and suckers freely. An oldy but a goody, it just keeps on producing and producing. Berry size is 14 mm with a shrub size of 8 ft.


Our Chokecherry Orchard

Garrington Chokecherry — Prunus virginana
Fruit size is large - good for processing. (8-10 mm) The bush matures to a height of 8 ft and fits inside a mechanical harvester. Garrington performs well in processing tests of Dr. Janet Panford. A delightful syrup can be made!  Check out our farm store and our winery!

Saskatoons - a New Super Fruit

Saskatoon berries can be considered as one kind of ‘Superfruit.’ The word ‘Superfruit’ refers to fruit that contains high sources of antioxidants. From a nutraceutical perspective, antioxidant-rich fruits have anti-cancer, anti-aging, and anti-heart problem effects on the human body. The benefits of antioxidant have contributed against cardiovascular and inflammatory diseases, and act as a protective guard to our immune systems.

The ORAC (oxygen radical absorbance capacity) value is one of the methods used to measure the total antioxidant activity in fruit. In the tables below, the ORAC values show Saskatoon berries are naturally high in antioxidants and rank highest in both fresh fruits and in fruit pulp relative to other common fruits.

Whole Fresh Fruit - ORAC

Fruit Pulp - ORAC

Research evidence shows that antioxidants found in fruits and vegetables may help reduce the risk of cancers. Studies also showed that there is a potential anticarcinogenic activity of anthocyanins in fruits and fruit products, and anthocyanins may possess multifaceted actions, including antioxidation and anti-carcinogenesis and may have inhibitory effects on colon carcinogenesis.

Anthocyanins Show Potent Anti-Obesity Potential

Anthocyanins, antioxidant pigments from fruit and vegetables, have a "significant potency" against fat cells and could be used for the prevention of weight gain, suggests a new study from Japan. 4

Nutraceutical Properties of Cherries

'Listen to Rick Sawatsky's research technician U. of S. and see what all the excitement is about!'

Quote "Researchers in Michigan have found that tart cherries, one of the parental species of dwarf cherries, contain compounds with antioxidant and anti-inflammatory properties. Cherries have been linked to beneficial health effects in that cherry growers, who eat six times the amount of cherries as the average American, have a lower incidence of cancer and heart conditions. The most active antioxidant compounds in the cherry fruit are superior to vitamins E and C and some synthetic antioxidants. The same researchers have speculated that the natural antioxidants in cherry fruit could be extracted for use in food processing. It is interesting to note that these superior antioxidants in tart cherries are anthocyanins that are associated with the bright red color. Our dwarf cherries have a more intense red color than Montmorency, the most commonly grown tart cherry in Michigan. Our dwarf cherry fruit has not been tested for antioxidant concentration, but it is reasonable to expect high levels.

These scientists also found that compounds from tart cherry fruit, have anti-inflammatory properties which support anecdotal information that tart cherries may relieve the pain of gout and arthritis. A family member reports relief from gout after eating our dwarf cherry fruit.

A food scientist in Michigan reports that adding tart cherry fruit to ground meat resulted in a 50% greater reduction in the formation of mutagenic compounds during cooking. This was compared to ground meat to which other antioxidant compounds had been added. Dr. Alden Booren, professor of Food Science and Human Nutrition at Michigan State University, says, "We found that tart cherries reduced the formation of mutagenic compounds by 90% - a 50% greater reduction than with the other compounds. They are the most significant source that we have found to prevent mutagen formation in ground beef. Our trained taste testers found the cherry-beef mixtures to be very desirable and had equal to or better flavor than those from lean ground beef. We also found that reheated ground beef with cherries was essentially devoid of oxidized or rancid flavors." He and other scientists believe that the antioxidant properties of tart cherries are responsible for these effects. For complete information, see the Cherry Marketing Institute" end of quote.

So what is a Nutraceutical, you ask? A nutraceutical is a food or food component considered to provide medical or health benefits. These foods assist in the prevention or treatment of disease. This is a new area of study, but scientists are now just proving that mom was right. She always said to eat your fruits and vegetables. Live long and healthy - Eat your berries!

Anthocyanin (flavonoids) Briefly Explained

Excerpt from: Willy Kalt, Agriculture, and Agri-Food Canada
Atlantic Food and Horticulture Research Centre

"An important group of health-promoting phytochemicals is the flavonoids. These compounds are particularly abundant in fruits, but also occur in vegetables. One notable group of flavonoids is the anthocyanins. The anthocyanins are pigments - they impart the red, blue, purple color to the peel of fruits such as Saskatoon berries, blueberries, strawberries, cranberries, etc. A good indicator of the anthocyanin content of fruit is the color intensity of its juice. For example, a blueberry juice would be much more deeply colored than say a strawberry juice, due to its higher anthocyanin content.

One important property of the flavonoids is that they are antioxidants. This means that antioxidant compounds like flavonoids may provide some protection to humans against the deleterious effect of oxidative stress. Oxidative stress has been strongly implicated in the development of a cardiovascular disease, many types and cancers, and certain neurodegenerative diseases."

Flavonoids have other health benefits. For example, flavonoids have a “blood-thinning” effect; they inhibit the aggregation of blood platelets which otherwise contributes to the formation of blood clots and the deposition of atherosclerotic deposits in blood vessels. As antioxidants, flavonoids inhibit the oxidation of LDL (low-density lipoprotein), and together these effects contribute to the general protective properties of these compounds.

The “French Paradox,” which is the unexpectedly low incidence of cardiovascular disease in high-risk groups (smokers with high-fat diets), has been explained by the high consumption of flavonoid-rich red wines in these populations.


Saskatoon Nutrients The Journal of Food Science – Volume 47 1982 Dr. G. Mazza

Saskatoons appear to be an excellent source of manganese, magnesium, iron, calcium, potassium, copper, and carotene. A 100 gm serving of fresh saskatoons will supply 88 mg. of calcium or 11 % of the Recommended Dietary Allowance.

Saskatoons can be considered a better source of calcium than red meats, vegetables, and cereals.

Saskatoons supply 33.8 % of the Recommended Dietary Allowance of manganese and 7% of the Recommended Dietary Allowance of copper.

Recent research indicates saskatoons have very high components of phenolics, flavonols, and anthocyanins.

Saskatoons are high in sugar, rich in Vitamin C, and also contain more than three times as much iron and copper in the same weight as raisins.

Excerpts  are taken from Linda Kershaw, Botanist, Lone Pine Publishing
Historically, native people used saskatoons for many things. The berries treated stomachache, liver trouble, sore eyes, and the pains and bleeding of childbirth. Dysentery, painful menstruation, and bleeding during pregnancy were treated with the inner bark or roots. The settlers adopted the Saskatoon as a medicine too. Diarrhea was treated with crushed green berries, and ripe berry juice was said to act as a mild laxative and to relieve an upset stomach. The inner bark was made into a brew for eyewash, which treated blurred vision from sun, dust, or snow blindness. If a pregnant woman was injured, saskatoon root tea was immediately administered.

Black Currants Excerpts from Pal Tamas, Leading Researcher and Plant Breeder of Sweden
“Black currants can rightfully be called the “King of the Berries” due to the intrinsic biological and nutrition-physiological values of its fruits…it contains several-fold higher concentrations of potassium, iron, vitamin C, organic acids, and biologically active plant phenolic compounds than other fruits. In this respect, the blackcurrants constitute a distinct group among the fruits. These compounds exert a synergistic effect on the human organism.

The different plant phenolic compounds, the so-called bioflavonoids, display a large diversity of biological functions in the human organism. The most important of these biological activities is the so-called vitamin P activity that has a vasodilatory effect and also affects the flexibility of the capillaries. Research has established the preventive and therapeutic effects of the biologically active compounds of black currants. Furthermore, they were also shown to stimulate digestive processes. It was determined that the blackcurrant has anti-inflammatory, anti-oxidative, and weak antibacterial effects, as well as protective effects on harmful radiation.

The biological effects of some of the biologically active compounds of black currants surpass known chemical compounds with similar effects. As a consequence, medicines and raw materials for medicines based on blackcurrant extracts have been put on the market. Clinical studies performed in Bulgaria, under the supervision of Tasev (1968), have shown that it is possible to use blackcurrants as a major therapeutic agent for the treatment of distinct diseases, instead of the dosage of conventional drugs.”

Currant seed contains high levels of GLA, gamma-linolenic acid. The deep rich color of black currant is a strong antioxidant.


Nutritionally Speaking, Berry Smart Says:

Seeds of black currants are rich in both omega-3 and omega-6 fatty acids. Fresh fruit has an abundance of vitamins A, B, and C and contains between 6 and 9% sugar. They are also full of antioxidants.

Quotes on Black Currant from Dr. Richard St. Pierre Native Fruit Specialist University of Saskatchewan

“Historically, black currant fruit, roots, and leaves have had many medicinal uses. Black currant fruit is very rich in vitamin C. Black currant juice, tea, and extracts have been used to treat sore throats (quinsy). Consequently, the name “squinancy berry” was adopted in Great Britain.

The leaves and buds of European black currants have been used as an anti-inflammatory drug. Various North American native tribes used the roots of the native black currant to treat many conditions, including intestinal worms, kidney problems, and uterine disorders. The fruit of one species was used as a mild laxative, while early settlers used root infusions to treat dysentery in cattle and fevers in people.

Oils extracted from leaf and flower buds of black currants have been used in cosmetic creams, lotions, and perfumes. Black currant seed is considered to be a potential source of omega-3 and omega-6 fatty acids for the treatment of asthma, premenstrual syndrome, skin conditions, and arthritis.

Black currant has exceptional nutritional value. Seeds are rich in both omega-3 and omega-6 fatty acids. Fresh fruit has an abundance of vitamins A, B, and C and contains between 6 and 9% sugar.”

Chokecherry (Prunus virginiana) (Excerpts from St. Pierre, 1993, Research Scientist and Director Native Fruit Development Program, University of Saskatchewan)

Here is Some History

Chokecherry was one of the most important plants used by the Plains Cree and Blackfoot. Just like saskatoons, dried chokecherries were ground with stones and used in soups, stews, and pemmican. The period during which the chokecherry was in fruit was referred to as “black-cherry-moon’. The Shuswap Indians mixed the fruit with bear grease to make colorful paint for pictographs. Canadian west coast natives ate chokecherry dried fruit with salmon or salmon eggs. The bark was boiled along with other ingredients to produce a remedy for diarrhea. A strong, black, astringent tea was made from boiled twigs and used to relieve fevers. Dried roots were chewed and placed on wounds to stop bleeding. Teas were made from the bark or roots and used to treat coughing, malaria, stomachaches, tuberculosis, and intestinal worms. Such teas were also used as sedatives and appetite stimulants. The fruit was used to treat canker sores, ulcers, and abscesses.

The wood of the chokecherry was used for tipi construction, bows and arrows, skewers, diggings sticks, pipe stems, and fire tongs. Navajo Indians thought of the chokecherry as a sacred plant, and used its wood to make prayer sticks.

The chokecherry was also utilized by European settlers in North America. Parts of the chokecherry were the basis of popular home medications. Teas made from the bark have long been used as a sedative and to alleviate coughs. Extracts of the berries and bark have been used as a flavoring agent for cough and cold preparations. Wild cherry bark was an officially recognized pharmaceutical from 1800 – 1975.


Nutritionally Speaking, Berry Smart Says:

A Ribes (Currant) renaissance is underway in North America! Black currants, highly toted for nutraceutical properties, have vitamin C content four times higher than citrus, potassium two to three times more than most fruit and 30 - 40 types of bioflavonoids, much more than most fruits. Consumption of Black currant nectar has shown to benefit the heart and circulatory system, kidney function, liver function, and the digestive system.

Black Currants May Help Thwart Alzheimer's

MONDAY, Jan. 23 (HealthDay News) — Compounds in black currants may help protect against Alzheimer's disease, according to a study in the current issue of Chemistry & Industry magazine.

Researchers found that these compounds — anthocyanins and polyphenolics — had a strong protective effect in cultured neuronal cells. Darker black currants contain more anthocyanins and are likely to be more potent.

"These compounds also work in hippocampal cells taken straight from the brain," researcher James Joseph of Tufts University said in a prepared statement. He said these protective effects would likely be reproduced in the human body and that these compounds may prevent or significantly delay the onset of Alzheimer's.

While previous research found that compounds in black currants acted as antioxidants, this is the first study to demonstrate that they may help protect brain cells. Exactly how they do this remains unclear, the study said.

"We have evidence that the compounds protect against Alzheimer's by influencing the early gene expression in learning and memory, which influences cell signaling pathways that help neuronal cells communicate with each other," Joseph said.

Berries 'Help Prevent Dementia'

British blackcurrants are said to be especially rich in anti-oxidants

Compounds in the common British blackcurrant could help prevent Alzheimer's disease, research suggests.
A study shows blackcurrants and their US cousins, boysenberries, are full of potentially beneficial anti-oxidant compounds.

Research in the Journal of Science Food and Agriculture found these compounds could block the cell damage, which leads to Alzheimer's disease.

The New Zealand team said the berries could prevent but not cure dementia.

Cancer and Aging

Alzheimer's disease is thought to be caused by the buildup of deposits of a protein in the brain.

These amyloid plaques are associated with damage to brain cells, which are eventually killed off.

It is this damage - known as oxidative stress - which the anti-oxidant compounds in the berries appear to combat.

The berries contain a cocktail of chemical compounds, including anthocyanins - which cause the deep color in blue and purple fruits - and polyphenolics - which can be found in red wine and chocolate.

Dilip Ghosh of the Horticulture and Food Research Institute of New Zealand tested the compounds on cultured human brain cancer cells.

'Confident'

They demonstrated in a test tube their ability to protect against the effects of oxidative stress - in this case, caused by adding the chemical hydrogen peroxide to the culture.

Oxidative stress is an important cause of brain degeneration as well as cancer and aging.

The researchers said: "The extracts of boysenberry and blackcurrant containing anthocyanins and phenolic compounds displayed significant inhibition against the oxidative challenge of hydrogen peroxide."

This can decrease the rate at which cells mutate and therefore give protection against age-related diseases, they added.

The results demonstrate that a specific fraction of blackcurrant is particularly effective.
Dr. Susanne Sorensen
Alzheimer's Society

Fellow researcher James Joseph of Tufts University said the effect was likely to be the same in humans.

He told Chemistry and Industry magazine: "I am confident that the Alzheimer's protective effect we've seen will bear out in live humans.

"Diet will never be able to cure Alzheimer's but could prevent it or at least delay its onset."

Head of research at charity Alzheimer's Society Dr. Susanne Sorensen said the study results helped to explain evidence that berries have a protective effect against a range of diseases.

She said: "The results demonstrate that a specific fraction of blackcurrant is particularly effective in this respect.

"However, the results cannot readily be transferred from this experimental system of cultures of well-characterized tumor cell lines to neurons nor to complete brains."
