Black Walnut Seeds (Juglans nigra) - (Zone 3) - 8 Walnuts

We're excited to offer black walnuts collected from Manitoba, selected for above average cold hardiness and nut production in a colder climate than typical walnut trees.  These hard to find mature trees in southern Manitoba have made it through some selection pressure to be hardy to the Canadian prairies, compared to walnuts imported from warmer provinces.

Black walnut can grow up to 80-90 ft tall, with a straight trunk and an open, rounded crown.They produce nuts in round, green husks about the size of an orange that drop in early October and inside is the edible black walnut.  The trees are attractive with compound leaves growing up to 24 inches long. Note that while other vegetation in our experience seems to grow just fine with other trees and bushes around, a walnut tree's roots produce a chemical called juglone, which can inhibit the growth of nearby plants.

*Note these require parcel shipping and are only available for shipping inside Canada

Seed Source: Manitoba
Cold Hardiness Zone: 3
Cold Stratification: 4 months cold
