Juglans nigra - The black walnut is one of the trees with the most potential for nut cultivation in Quebec's climate. It is sought after for the establishment of nut orchards, shelterbelts and the enrichment of woodlot.
Petite-Nation selection These seedlings come from an open-pollinated selection of the best walnut trees we've evaluated in Petite-Nation. Although tasty, the nuts from this selection are smaller than commercial nuts. They come from a line of productive parents in zone 3b. Ideal for colder regions and forest plantations.
Commercial black walnut orchard selection These seedlings come from a commercial walnut orchard in zone 4b. The mother trees are therefore the best-performing cultivated varieties (Spark 127, Emma K, Sparrow, etc.). These seedlings are ideal for producing high-quality walnuts. They are likely to be the mother trees of the next selections of Quebec cultivated varieties.
Diversified orchard selection These seedlings come from a commercial Quebec orchard in zone 5b. The mother trees are the best-performing cultivated varieties of black walnut, but the pollen cloud surrounding them is more diverse. Within this orchard are black walnut trees, but also the best varieties of butternut, Japanese walnut and hybrid walnut. Although black walnut has a preference for intraspecific pollination (read within the same species), some seedlings may be the result of interspecific pollination (read between two different species)! Keep a close eye on these offspring... They may conceal some rare botanical treasures!

Biotope
Biotope
It adapts to several types of soil, provided that it is well drained. A plantation in full sun and in a deep soil is necessary for the growth and the production of fruits. It is ideal for shelterbelts, permaculture orchards or woodlots. The tree casts only partial shade under its leaves.
Wood
Wood
The uses of its hard, rot-resistant wood are varied. It is sought after in cabinet making for luxurious furniture, pianos and sculptures. It is recommended to establish 6 to 10m spacing for log harvesting and 15m spacing for veneer production. Annual pruning is required to establish a good bole. In the case of close plantings, successive thinning is necessary to maintain good growth.
Size and shape
Size and shape
The tree can reach 10 to 25m in height and a width of 10 to 15m without competition.
Pollination
Pollination
Self-sterile. Ideal fruiting is achieved by planting at least two trees of different cultivars. The nuts of the black walnut are tasty and have a unique taste. It is necessary to extract their husk, dry them and use a nutcracker to extract the flesh.
