All Zone 4 (or Hardier) Plants

Species: Vitis vinifera x V. rupestris x V. ripraria x V. labrusca

History: Osceola Muscat/ES.8-2-43 was bred by renowned grape breeder Elmer Swenson as part of his effort to mix French and North American grapes to create high-quality varieties that grow well in cooler climates. Osceola Muscat is a cross between four different species: Common grape (Vitis vinifera), Vitis rupestris, Riverbank grape (Vitis riparia) and Fox grape (Vitis labrusca). Swenson bred it on his farm near Osceola, Wisconsin and in 2010 the variety was named after the town. The grape's alternate name, Muscat de Swenson, is named after Swenson himself who passed away in 2004.

Why We Grow It: Osceola Muscat produces loose clusters of seeded, intensely aromatic grapes with notes of peach and apricot. The small-medium, thin skinned fruit is suitable for fresh eating or juice and wine. This is one of the hardiest 'muscat' varieties available and is relatively vigorous.

History: German plums are a European variety characteristic of the kind grown in central Europe. Although not much is known about its history, it is believed this variety is at least a couple centuries old. 

Why We Grow It: A juicy, freestone plum with an aromatic, sweet flavour. They are great for fresh eating and due to their drier than average nature, are great for baking into traditional German plum desserts. They keep for 2-4 weeks refrigerated, providing ample time to enjoy them fresh or find that perfect recipe. 

The photo of the plums in hand compares 4 larger Italian plums on the upper right, to 2 smaller German plums on the lower left.

History: Idared apples were developed at the University of Idaho Agricultural Experiment Station in 1942. Although its flavour is generally considered average, its excellent storage qualities have made it one of the most popular apple varieties in North America.

Why We Grow It: Idared's best quality is its ability to easily last six months when stored in a fridge, potentially until June under optimal storage conditions. The flesh tends to be softer and is white with some tinges of green. The flavour is described as sprightly, moderately acidic, and tangy, and this apple boasts a high Vitamin C content. It is great for baking and making applesauce. The tree's naturally somewhat smaller size makes Idared easier to prune and train.

Species: Amelanchier alnifolia (aka Western Serviceberry)

History: Smokey (sometimes spelled Smoky) likely originated in Alberta. This productive variety was once the main cultivar grown in Canada commercially.

Why We Grow It: Smokey saskatoon berries are optimal for the fresh eating market with a mild sweet flavour. These berries are a great substitute for blueberries. Smokey is one of the best yielding varieties, and grows up to 12 feet tall. Saskatoons by nature are slow growing, and while they will bear fruit in 1-3 years, it can take up to 15 years for a full crop.

Species: Aronia melanocarpa

History: Viking was developed in Finland around the 1980s, likely looking to increase productivity. They succeeded and Viking is now the most productive of all aronia cultivars.

Why We Grow It: With slightly larger than average berries, very good flavour, and the best productivity of all aronia berries, Viking is a hard variety to turn down. Like other aronia berries, they can be a bit tart for fresh eating but are great when used for cooking, baking, wines, jams, etc. While the berries ripen in August, they can hang onto the bush for a couple months and tend to sweeten over time.

Species: Actinidia kolomikta

History: September Sun is a Russian variety that was selected for its ample crops of large fruit. Its Russian name is Sentyabraskaya which translates to 'September' in English with a bit of a feminine sound to the name. 

Why We Grow It: September Sun is known for producing good-size crops of large, sweet fruits. These grape-like kiwis are a delightful treat for any yard, especially for growers in a colder area! It is also a great ornamental plant, featuring pinkish-white and green variegated leaves. 

Species: Salix sp, most likely Salix discolor

History: Pussy willows are native to North America, Europe, and Asia and are culturally significant in all three continents. They are a New Years decoration in China and Iran and have been used in various sects of Christianity for purposes such as replacing palm fronds as a decoration for Palm Sunday in Europe and America where palms do not grow. 

Why We Grow It: A fluffy signifier of spring, these cute willows are also a great early pollen source for bees and have medicinal uses.

History: A highly regarded cider apple of Normandy, France, where it has been grown for centuries. This cultivar is one of the traditional cultivars in the production of calvados (a brandy made from apples and sometimes pears) in the Pays d’Auge region.

Why we grow it: This cider apple has a unique spicy flavour that is high in tannins, low in acidity, and low in sugar. With it's rich history and beautiful brass coloured juice, this cultivar is a must in every well-rounded cider orchard.

History: In the 1830s in Lancaster County, Pennsylvania, a seedling apple tree grew beside the smokehouse of William Gibbons. Perhaps it sprang from a core that some one had tossed there while they tended the fire. Who knows? What we do know is that the aptly named Smokehouse was commonly grown in the area until its popularity waned as sweeter apple varieties appeared on the market. Still, this variety has stood the test of time due to its great flavour. 

Why We Grow It:  Traditionally Smokehouse apples are picked a little early and used for baking, but if they're allowed to ripen fully on the tree, some people have described the balanced flavour as being “like drinking fresh-pressed cider!”. 

Species: Ribes rubrum

History: Developed in Holland, White Pearl currants, like all white currants, are actually an albino mutation of red currants. This variety has been popular in Europe for quite some time, although aside from its place of origin it appears there is little information on how it came to be. 

Why We Grow It: These delicate translucent berries are white with a pinkish-gold hue, making them delightful to see growing in the garden. They have sweet and mild flavour that is slightly floral. The plant itself is quite cold hardy and bears prolific crops.

History: Duchess of Oldenburg, or Duchess as we like to call it, originated in the 1700s in Russia. It spread to other countries where it became popular, especially in Victorian England. Its popularity was so great that at one point it was used as a reference cultivar when evaluating other varieties of apples. It is also likely the parent of several other varieties such as Northern Spy.

Why We Grow It: Duchess boasts an attractive fruit that is striped and mottled red over light green. Although these apples don't store well, the flesh is soft and is excellent for pies and applesauce. The trees themselves are quite hardy and disease resistant.

History: Thunderchild is a crabapple that was developed by Percy Wright, a prairie plant breeder in Saskatoon, Saskatchewan. Although it is unknown when exactly Thunderchild was created, it likely came about in the 1900s and can still be seen as a common ornamental tree in the area.

Why We Grow It: Thunderchild makes for a lovely ornamental tree with a profusion of pink blossoms in the spring and deep red foliage. The tiny dark red fruits it produces can be used in cider blends and to make jellies with a gorgeous orange hue. The tree is quite cold hardy and generally disease resistant. 

Species: Ribes uva-crispa x Ribes missouriense

History: Pixwell was developed at the North Dakota Experiment Station in a gooseberry breeding program that began in 1920. A cross between Oregon Champion and Ribes missouriense, the variety was eventually released in 1932. Pixwell was named for it's less thorny nature - as in smaller and less thorns than most gooseberries, especially as it grows older - which makes it easier to pick the berries.

Why We Grow It: Aside from living up to its name, Pixwell produces green berries that turn a lovely shade of pink to deep plummy-purple-red once they are fully ripe - though you can use the green berries for tangy chutneys and the pink stage is nice fresh too. The medium berries have sweet flesh and tart skin, and are great for fresh eating, pies, and preserving.

Species: Armoracia rusticana

History: Horseradish originated somewhere in the Mediterranean and has been well known since ancient history, appearing in writings from Ancient Greece, Ancient Rome, and the Renaissance. It has historically been used for both culinary and medicinal purposes in Europe and was introduced to North America by European colonizers where indigenous peoples also adopted it for medicinal use. Today, horseradish is commonly grown around the world and used in cooking or to make sauces. An enzyme in horseradish also has applications in molecular biology and biochemistry! 

Why We Grow it: Horseradish is a root vegetable with a distinctly pungent and sharp taste. As a result, it is most often used in cooking and making sauces/condiments. It is a hardy vegetable and has a tendency to spread through the garden so extra care should be taken to keep it contained when planting it.

History: Honeygold apples were developed by the University of Minnesota and introduced in 1970. It is one of nearly 30 varieties that have been developed by the university's breeding program since it began in 1888. This apple is a cross between Golden Delicious and Haralson, designed to combine the taste of the former with the cold hardiness of the latter. Honeygold is also famous for being mistakenly identified as one of the parents of Honeycrisp, although that has since been rectified.

Why We Grow It: With the sweet taste and appealing look of Golden Delicious but the cold hardiness of Haralson, this is an excellent apple for anyone living in colder hardiness zones. It is great for fresh eating as well as making pies and applesauce. The tree is also somewhat scab resistant.

Species: Vaccinium corymbosum

History: Blueray higbush blueberry was introduced in 1941, although there is little other information on its origins. It may have originated in New Jersey where blueberry cultivation began.

Why We Grow It: Blueray produces an abundant crop of very large berries with good flavour. This cold hardy variety is great for home growers! Blueberries are great for baking, for example Steph made some wonderful black currant and blueberry tarts that are pictured here!

Species: Juglans cinerea or hybrid. NOTE: Butternuts are known to hybridize readily with other closely related species so there is no guarantee on whether these seedlings are pure, though the mother trees appear very true to type. 

History: Butternut is an endangered tree native to southeastern Canada and the eastern United States where they grow naturally along sunny stream banks with rich, well-draining soil. The nuts have been used as a source of food and made into a butter-like oil by indigenous peoples. The trees have also been used for making syrup, furniture, and woodcarving. Unfortunately, Butternuts are highly endangered today due to Butternut Canker which has decimated their population within two decades. 

Why We Grow It: By planting endangered species, collectively we can help Mother Nature potentially find a naturally resistant variety of Butternut. The nuts are quite similar to other walnuts but with a milder flavour. They can survive in zone 2, but they must be planted somewhere zone 3 or warmer to produce nuts. The sap can be boiled to make walnut syrup, which tastes very similar to maple syrup but with notes of caramel and butterscotch.

Be mindful of the juglones in the in the roots/nut husks, they are toxic to many other species. They require a buffer of about 50'/30m from the edge of the trees canopy for juglone-sensitive plants. This article from The Garden Hoe has a helpful list of plants that tolerate juglones. However there are recent (2019) studies showing healthy soil high in organic matter and mycorrhizal fungi actually reduce the toxicity of juglones suggesting many plants can grow below juglans species in a healthy ecosystem - it will be interesting to see more study done in this area!

Species: Vaccinium angustifolium

History: BB4 lowbush blueberry was discovered growing wild in a bush near a tissue culture lab near the small municipality of L'Ascension-de-Notre-Seigneur in the Saguenay-Lac-Saint-Jean region of Quebec. Impressed with the quality and flavour, the lab decided to propagate these wild blueberries.

Why We Grow It: BB4 produces medium to large powder-blue berries, with a tasty, sweet flavour. The berries grow in nice clusters, making picking easy. Blueberries are great for baking, for example Steph made some wonderful black currant and blueberry tarts that are pictured here!

History: Lodi is a cross between Yellow Transparent and Montgomery Sweet created at the New York Agricultural Experiment Station in Geneva, NY, and released in 1924. Although it is not suitable for commercial production due to its poor keeping qualities and tendency for the flesh to crack in storage, it is still commonly grown by homeowners in the southern US today.

Why We Grow It: If you're looking for an early apple to get started on making applesauce, Lodi is the way to go! These large yellow-green apples are ready to harvest by the end of July and do not bruise as easily as their Yellow Transparent parent.

History: Once one of the most popular commercial apples in the United States, Ben Davis apple trees were planted across the continent following its discovery around 1800. Due to its firm fruit and excellent keeping qualities, this apple was extremely easy to transport over longer distances which led to its popularity. Once storage and transportation improved, this apple was slowly replaced with better tasting varieties and it is now a relatively rare find. It's also a parent to Cortland.

Why We Grow It: The mellow, sub-acidic, mildly aromatic red fruit is not quite as flavourful as some apples but it stores exceptionally well, lasting into spring. Flavour improves in storage, like many heritage apples. The trees are reliable and heavy croppers, earning them the nickname of 'mortgage-lifters' when they were grown commercially. 

Species: Vaccinium corymbosum

History: Elliott originated in 1947 when Dr. George Darrow of the USDA first bred it. Elliott, and the other blueberries Dr. Darrow bred, were first evaluated by Dr. Arthur Elliott and then by members of the USDA such as Arlen Draper who has bred numerous blueberry varieties. It was released in 1973, over 25 years after the it was originally grown. Elliott was selected for the good quality of its fruit and its exceptionally late ripening time, making it a great variety for extending the blueberry season. It was named Elliott to honour Dr. Elliott's contributions to blueberry breeding efforts. 

Why We Grow It: Elliott produces large berries with a mild sweet flavour late in the season. They are great for fresh eating, cooking, baking, and preserving! The bush is very productive and the firm fruit stores well. For those who want to enjoy fresh blueberries for as long as possible, Elliott is an excellent choice due to its very late ripening time!

Species: Juglans nigra or hybrid. Our seeds are collected from trees that may have been cross-pollinated by closely related species so the resulting seedlings may be hybrids. 

History: Native to much of the eastern and central United States and southern Ontario, Black Walnut has long been used as a source of food, dye, lovely dark wood, and as an ornamental tree. Although it is said to have a better flavour than the English walnut, the Black walnut remains less popular due to the increased difficulty of harvesting the nut meat from within the husk. Black walnut is also infamous for being allelopathic, meaning it secretes toxic chemicals (juglones) into the soil to reduce plant competition. 

Why We Grow It: Black walnut is a beautiful tree that produces nuts with a stronger flavour than that of English walnuts. The sap can be boiled to make walnut syrup, which tastes very similar to maple syrup but with notes of caramel and butterscotch. Also, the husks can be used in brewing beer! 

Be mindful of the juglones in the in the roots/nut husks, they are toxic to many other species. They require a buffer of about 50'/30m from the edge of the trees canopy for juglone-sensitive plants. This article from The Garden Hoe has a helpful list of plants that tolerate juglones. However there are recent (2019) studies showing healthy soil high in organic matter and mycorrhizal fungi actually reduce the toxicity of juglones suggesting many plants can grow below juglans species in a healthy ecosystem - it will be interesting to see more study done in this area! 

History: Golden Nugget was created more or less by accident when Golden Russet and Cox's Orange Pippin were crossed at the Kentville Agricultural Station in Nova Scotia in 1932. Despite being an accident, once researchers realized how flavourful this variety was they continued to raise it and eventually released it in 1964. Although a delicious apple, its small size prevented it from attaining true commercial success.

Why We Grow It: It is prized for its incredible flavour which is super sweet and tangy like a pineapple. Along with being great for fresh eating, it is also suited for cider. The tree itself boasts decent disease resistance.

Species: Vaccinium corymbosum

History: Patriot was developed by the USDA and Maine Agriculture Experimental Station where it was first bred in 1954. It was selected for its cold hardiness and resistance to root rot. Patriot was released in 1976 and given its name to mark the 200th anniversary of the signing of the Declaration of Independence. 

Why We Grow It: Patriot produces large berries with excellent flavour that are a bit on the softer side. The fruit ripens early in the season and is great for fresh eating, baking, preserving, and freezing! It is more tolerant of the cold and of wet soils than other blueberries and can be grown even in a clay soil. 

Species: Actinidia arguta

History: Changbai Giant kiwis were discovered by the Changbai Mountain Research Institute of the Chinese Academy of Agriculture near the North Korean border. The variety was likely collected and propagated due to its unusual round shape and excellent flavour. Named for the Changbai Mountains where it was discovered, its name translates literally from Mandarin as 'perpetually white.' It is also named for the exceptionally large fruit it produces.

Why We Grow It: Aside from its interesting origins, Changbai Giant also boasts unusually shaped kiwis compared to other varieties: round like an apple rather than more oblong like other hardy kiwis. The fruit is also very sweet and the plant itself is a little hardier than some other varieties. Like other female varieties, it can produce a large crop of fruits and it is recommended that the vine be grown on a trellis or other kind of support. 

History: Goldcot was bred by researchers in Michigan's snowbelt with the goal of creating a hardier apricot that could withstand harsher winters. They succeeded and Goldcot apricots were introduced in 1967. 

Why We Grow It: Both an early and notably hardy cultivar, Goldcot is known to be productive and dependable. The flesh of the fruit is drier than other apricots and has a slight tangy taste that is good for both fresh eating and canning. The tree has a natural semi-dwarf growth habit, great for anyone looking for a smaller apricot tree.

History: The Geneva crabapple was developed in the 1930s in collaboration with the Ottawa Experimental Farm and the New York State Agricultural Research Station based in Ottawa. The creation of this crabapple was head by Isabella Preston who specialized in creating cold-hardy ornamental plants.

Why We Grow It: This attractive crabapple has deep maroon flesh. The tree itself is quite visually appealing, sporting red leaves and bright pink flowers in the spring. The taste is reminiscent of rhubarb and is suitable for cooking as well. As it is a low sugar/high acid juice, it is best blended with another high sugar variety for cider. It also adds a nice red hue to blends.

History: Cupid is a part of the Romance series of dwarf sour cherry bushes developed and released by the University of Saskatchewan in 2004. Their goal was to create cold-hardy, dwarfing bushes with good quality fruit. Cupid was likely selected for its good flavour and unusually large cherries, the largest in the Romance series.

Why We Grow It: These dark red, cold-hardy cherries have a sweet-tart flavour that can be enjoyed fresh for fans of a more astringent flavour or used for cooking, baking, and preserving. Cupid has the largest cherries of all the dwarf sour cherries in the Romance series and also ripens the latest, helping to extend the season.

History: Norkent was bred as a cross between Haralson and Rescue at the Morden Research Station. It was one of tens of thousands of seedlings sent across the prairies as part of the Prairie Fruit Breeding Cooperative initiative by Agriculture and Agri-Food Canada in the 1960s. It was planted at the University of Alberta before being moved again to a backyard in Edmonton once the university ran out of space to it grow. 

Why We Grow It: This pleasant and aromatic apple is one of the best fresh eating apples for colder climates! The flesh of this red apple is crisp and said to taste like a cross between an apple and pear.

History: Melba was developed by W.T. Macoun at the Central Experimental Farm in Ottawa in 1898. In 1924 it was released commercially and three years later received the Silver Wilder Medal from the American Pomological Society. 

Why We Grow It: Melba is a lovely early market apple or backyard tree for making applesauce! The fruit is yellow with crimson flush and the crisp, white skin has a very sweet flavour.
