Buartnuts (Juglans x brixby) are a hybrid between the heartnut (Juglans ailantifolia var. cordiformis) and the North American butternut (Juglans cinerea). They combine the flavour of the butternut and hardiness of the heartnut. Buartnuts were first bred in British Columbia, Canada in the early 1900s. They 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 unpredictable in terms of nut production and quality, grafted trees always come true to form. 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 (60-100cm high) €40 ea
Cultivars
Mitchell
Medium size nut, heartnut shaped shell, fairly good cracking. Canadian origin. Partially self-fertile but will also be pollinated by most heartnuts but especially Campbell CW1 and Imshu.
Buartnut seedlings
One year old plants raised at our own nursery from selected seed from Ontario Province, Canada. Unlike the named cultivars of Juglans x brixby, these seed-grown trees may not produce heavy crops of nuts but have much better prospects than seed-grown walnut. 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.
25-40cm €2.40 ea
