'Dooley Hybrid' F2 Seedling of the 'Dooley Hybrid' mother tree (J. regia x J. nigra) in open pollination with other Juglans regia. The nuts on the mother tree are so thin that they can be broken off by hand. Seedlings of these trees will be very interesting for the quality of their nuts, but will be less hardy. We recommend planting them in zone 5b and above with at least two trees of this cultivar to ensure better pollination.
Seedlings of J. Ailantifolia var. cordiformis x Juglans Spp.
These seedlings come from a Quebec commercial orchard in zone 5b. The mother trees are the best-performing cultivated varieties of Japanese walnut, but the pollen cloud surrounding them is very diverse. The orchard includes Japanese walnut trees, as well as the best varieties of butternut, black walnut and hybrid walnut. The mother trees of this selection are known as 'Mitchell', 'Imshu', 'Stealth', 'Locket' and 'CW3'. Although the Japanese 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)! Japanese walnut tends to hybridize with butternut. Keep a close eye on these offspring... It may conceal some rare botanical treasures! These seedlings should be planted in zone 4b and above.
Biotope
Biotope
It adapts to many types of soil, provided it is well drained. Full sun and deep soil are necessary for growth and fruit production. It is ideal for windbreaks, permaculture orchards or woodlands. The tree casts only partial shade under its leaves.
Wood
Wood
Its hard, rot-resistant wood has many uses. It is sought after in cabinetmaking as a substitute for black walnut for semi-luxury furniture, pianos and sculptures. We recommend 6-10m 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.
Pollination
Pollination
Self-sterile. Ideal fruiting is achieved by planting at least two trees of different cultivars. Hybrid walnuts are tasty and have a unique flavor, fatter and less fragrant than black walnuts. They are reminiscent of Japanese walnut and butternut. It is necessary to extract their husk, dry them and use a nutcracker to extract the flesh.
