Hazelnut Hybrids, Northern
Sorry, no hazelnut trees can be shipped to the western United Statesor British Columbia due to restrictions by USDA and Agriculture Canada.
Our Northern hazels were selected from seed sources and crosses made for cold climates. Our seed sources include C. heterophylla hybrids (Asian hardy) as well as original crosses made at Morden Experimental Farm in Manitoba. This work is being carried on at the University of Saskatchewan. The seedlings and layered selections were open pollinated in our diverse hazelnut orchard. Nut and plant size of the progeny are bigger than the parent trees, but the trees are smaller than the standard European varieties. Our selected layered trees are highly blight resistant. We expect the seedlings to be at least 70% blight free too. Mature tree size is about 3-4 m tall and 3-4 m wide (10-14 ft). We consider them hardy for zone 3b, possibly 3a.

These C. Heterophylla hybrids are open pollinated crosses from our genetically mixed hazelnut orchard. Nuts ripen in late August.Suited for climate zones 4a to 8.
Our parent seed for this strain was grown in Saskatchewan where the less hardy trees of the Manitoba crosses were weeded out. The crosses were made by the Director of the Morden Experimental Farm in Manitoba. He crossed the prairie adapted native American hazel with breeding selections from the Geneva NY breeding project and distributed the off-spring across the prairies. The University of Saskatchewan is continuing with the hazelnut work. Blight resistance seems very good. Nuts ripen in late August. Suited for climate zones 4a-7.
These are hazel hybrids crossed with European hazels with years of exposure to the Wisconsin & Minnesota climate. They are productive trees with moderately thick shells. There is wide variation in tree size, nut size and the ease of husking. Suited for climate zone 3-8.
Our native American hazel tree is pollinized by surrounding hazel selections. The seedlings from this tree that we planted in our orchard have begun to produce. The nuts are all several times larger than the nuts from the parent tree, but the trees are just as productive as the parent. The nut size and shape resembles the pollen parent. The mother tree is less than 1.5 metres tall. The offspring are all larger trees than the parent, so far over 2 metres tall. We consider the seedling trees to be hardy for zones 4-7.
'Crimson' is a hardy red leaf hazel, possibly the most hardy ornamental hazel cultivar. It is a 'Wisconsin source' hazel with deep red leaf colour and large frilly husks that remain red until harvest in late September. It is expected to grow to about 2 metres tall. It is hardy from zone 4-8.
'Het E' is an 'Asian/Quebec' source hazel. It has good blight resistance but is susceptible to bud mite. Sprays are registered for bud mite control in Ontario. The tree is productive, hardy and about 3m x 3m in size (10' x10'). The nut is medium size, round and well filled.
'AldaraTM' is a medium size "Asian/Quebec source" tree growing to about 3-4 m tall and spreading about 3 m (12' tall & 10' wide). It is very productive and highly blight resistant. It is being tested as a pollinizer variety for later ripening commercial cultivars and as a main crop cultivar. The alleles are 25 and 27. It can be matched for pollination with any hazelnut that does not share these allele numbers.The nuts are medium size, round and ripen late August. Suited for climate zones 3b-8.
'AndrewTM' is a medium size "Asian/Quebec source" tree growing to about 3-4 m tall and spreading about 3 m (12' tall & 10' wide). It is productive and highly blight resistant. It is being tested as a pollinizer variety for later ripening commercial cultivars. We have only allele 27 identified in the pair so far. The nuts are medium size, round and ripen late August. Suited for climate zones 3b-8.
'Northern Blais’TM was selected by a grower in zone 4 in Quebec who originally purchased seedling northern hazels from our nursery. The ortet was returned to us for trial testing and propagation. The nuts are medium size, round, well filled. In research trials in Wisconsin and Minnesota, it was selected as an outstanding tree for hardiness, production and blight resistance.
Suitable for climate zones 4-7.
'Marion' is a medium size "Saskatchewan source" tree growing to about 3-4 m tall and spreading about 3 m (12' tall & 10' wide). It is productive and highly blight resistant. It is being tested as a pollinizer variety and a possible main crop cultivar. The nuts are medium size round and ripen late August. 'Marion' has alleles 14 and 25, so it should not be matched with hazelnuts with these same numbers. Suited for climate zones 3b-8.
'Frank' is a medium size "Saskatchewan source" tree growing to about 3-4 m tall and spreading about 3 m (12' tall & 10' wide). It is productive and highly blight resistant. It is being tested as a pollinizer variety as well as a main crop cultivar for colder zones. The nuts are medium size round and ripen mid August. One allele, number 14, has been identified so far, so it should not be matched with hazelnut trees that share this allele. Suited for climate zones 3b-8.
'Joanne' is a 'Saskatchewan' source hazel. It has good blight resistance but is bud mite susceptible. Sprays are available in Ontario for bud mite control. The tree is about 3m x 3m in size (10' x10') and a good producer of medium size round nuts. 'Joanne' has alleles 2 and 14, so it should not be matched with a hazelnut that has these alleles. It is hardy for climate zones 4-8.
'Julia' is a 'Saskatchewan' source hazel. It is blight and bud mite susceptible but still outproduces most other northern hazels. Sprays are registered for blight and bud mite control in Ontario, but pruning out the blighted limbs is also an option. The tree has proven to be hardy in Wisconsin. The nuts are large and well filled.'Julia' has alleles 11 and 14, so it shoulds not be matched with hazelnuts that share these numbers. It is hardy for zones 3b-7.
