Fruit and Nut
Buartnuts (Juglans x brixby) are a natural hybrid between the heartnut (Juglans ailantifolia var. cordiformis) and the North American butternut (Juglans cinerea). They combine the flavour of the butternut with the hardiness and disease resistance of the heartnut. Wild buartnut seedlings are often found growing in localities of North America where heartnuts were planted alongside the butternut. From the early 1900s onwards, growers began selecting seedlings with specific qualities, and from these developed distinct varieties. Buartnuts are largely unknown in Europe. They have the potential to do well in Ireland, particularly in the warmer and drier parts of the country.
The trees offered are not grown from nut but are propagated vegetively by grafting fruiting scions of known cultivars onto seedling rootstocks.
Unlike trees raised from nut, which are unreliable in terms of nut production and quality, and take many years to reach nut bearing age, grafted trees always come true to form and begin cropping at a young age. In order to facilitate pollination, it is advisable to plant more than one cultivar, or plant alongside heartnuts.
Buartnuts grow into big trees so should be spaced at 10-12 meters.
Young grafted trees supplied, 30-45cm, 45-70mm, 70-100cm and 100cm-140cm
Two year old plants raised at our own nursery from selected seed from Ontario province, Canada. Unlike the named cultivars of Juglans ailantifolia var. cordiformis, these seed-grown trees are very unlikely to produce reliable crops of nuts. Vigorous and strong, they will grow into fine large specimen trees suitable for timber production. The trees may also be used for rootstock for grafting purposes. 50-80cm €9.50 ea.
