All Zone 4 (or hardier) Plants

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!”. 

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: Juglans nigra

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: 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.

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. 'Butternut' became a derisive term for people living in the southern US since their clothes were dyed using butternuts, and the name later applied to Confederate soldiers. 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!

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: Caragana arborescens

History: As the name implies, Siberian pea shrubs are native to Siberia but also parts of China, Mongolia, and Kazakhstan. They came to the US with Eurasian immigrants who used the pods as a source of food while traveling. It has been planted ornamentally and as bonsai, and can be used as erosion control. It is also unfortunately invasive in some parts of the US.

Why We Grow It: A classic permaculture plant! Siberian pea shrubs are nitrogen fixing, very hardy, disease and drought resistant, and, above all, edible. The flowers and young pods can be eaten fresh while the older pods are cooked. The plants are also attractive to pollinators.

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.

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: 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.

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. 

History: Prima is one the apples developed from the collaborative PRI disease-resistant breeding program run by Purdue University, Rutgers University, and the University of Illinois. It was introduced in 1958 but unfortunately is no longer fully scab resistant due to the fungus evolving to overcome the resistance since then.

Why We Grow It: Another great apple for organic production and excellent for the backyard or farmer’s market sales! This apple is sweet, juicy, and flavourful and boasts good disease resistance..

Species: Hippophae rhamnoides

History: Sea buckthorn is native to parts of Europe and Asia where it has been a source of food, medicine, and fodder for centuries. These seedlings were grown by us so it will be a bit of a surprise to see what the mature plants are like!

Why We Grow It: If you're looking for a dense, fruiting bush, look no further! These cold-hardy plants are grown from seed, and unlike cultivated varieties it is uncertain whether each seedling is male or female. The nodules on their roots help fix nitrogen into the soil, and the resilient plants are salt tolerant. They can withstand the juglones from walnuts and will reach up to 6 meters tall, forming virtually impermeable thickets if left to their own devices. The berries have a wide range of uses and the leaves can be enjoyed in tea.

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: As the name suggests, Mount Royal plums originated in the Montreal area where it was either found by French colonizers as a wild chance seedling or intentionally bred by Jesuit missionaries and French colonizers using plums brought over from Europe. Either way, the result is a lovely plum hardy enough to survive Canadian winters.

Why We Grow It: This European plum is a Canadian classic of excellent flavour and good cold-hardiness. The fruit is blue-skinned with jammy yellow flesh that is both sweet and spicy. The tree produces heavy crops. 

History: Little is known about this particular variety aside from that it's a Damson plum that originated in Sweden. 'Krikon' is the Swedish word for 'damson.'

Why We Grow It: Although its history is a bit of a mystery, we can certainly tell you that this is the best plum variety for very cold regions. It produces small round deep purple fruit that are good for cooking, preserving, and making jam. The flesh has a spicy, sweet flavour although some do not find it that great for fresh eating. Compared to regular Damson's Krikon Damson is a bit smaller, and more flavourful.

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!

History: Brown Snout was discovered on a farm in the UK in the mid-1800s. Its name comes from the brown russet around its calyx. H.P. Bulmer, a cider-making company, further propagated and spread this apple in the UK where it is still used today.

Why We Grow It: This medium bittersweet cider apple has small, uniquely coloured fruit that are sweet, slightly astringent, medium-tannin, and have low acidity. 

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.

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.

Species: Aronia melanocarpa

History: McKenzie was created by the USDA who, in 1976, planted several seedlings of the variety to evaluate its performance. It was named 'McKenzie' in honour of its first planting site in North Dakota, possibly named after McKenzie County specifically. The variety was officially released in 2008.

Why We Grow It: McKenzie boasts vigorous growth and good production, reliably producing firm blue-black fruit that is tart with an earthy taste. The berry clusters are easy to pick and have a wide range of uses!

History: Maiden's Blush was first described in New Jersey in 1817 although it had already been popular in Philadelphia markets for some time. It likely originated around New Jersey in the late 1700s. Maiden's Blush continued to be commonly grown in the southern US through the early 1800s. 

Why We Grow It: Maiden's Blush's uniqueness is still worthy of attention today, its flavour being an interesting mix of citrus-like acidity and sweetness that stand out among other apples. While it is good for fresh eating, particularly after a few weeks off the tree, it is most well known for cooking, baking, and drying due to its non-browning qualities.

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: 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: This English cider apple originated in and was named after Rodney Stoke, a small village in Somerset, England. It was discovered around 1920 and has been popular in England since. 

Why We Grow It: Stoke Red produces a great bittersharp juice that is well-regarded for cider making. As an added bonus, it is a heavy cropper and resistant to scab.

History: Haralson apples were developed at the University of Minnesota in 1922 and named after Charles Haralson who was superintendent of the university's fruit breeding farm. It is one of almost 30 apple varieties the university has developed in its breeding program since it began in 1888.

Why We Grow It: The skin of this variety is striped red with russet dots and the flesh is white, juicy, and of pleasant albeit mild flavour. Haralson boasts excellent cold hardiness and general disease resistance.

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: Douce de Charlevoix (translated from French as 'sweet Charlevoix') was discovered by Claude Jolicoeur in a Quebecois village in the county of Charlevoix in the 1990s. He has since dubbed it a 'first class early cider apple' and in 2015 a cider blend using 40% Douce de Charlevoix won a bronze medal at the GLINTCAP competition. 

Why We Grow It: This apple is quite attractive with orange-red stripes across green skin and makes an excellent juice with a notable bitter taste. In general this apple has medium tannins, some sweetness, and very little acidity. The tree itself is also quite vigorous and hardy.

History: Tremlett's Geneva Bitter (aka Geneva Tremlett's Bitter) come from a tree that was believed to be Tremlett's Bitter, an English cider variety. It was imported to Geneva, New York from England in the 1960s but at some point there was a mix-up and the mistake was only uncovered after many American growers had received scions from the erroneous tree.

Why We Grow It: Although this isn't the traditional bittersweet cider apple popular in England, Tremlett's Geneva Bitter still produces a good quality bittershap cider. Some say it is even better than the original!

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.
