Hybrids between the butternut and heartnut. They combine the adaptability, cold tolerance and sweet flavour of the former with high yields and easily cracked shells of the latter. Large trees which need sun and a well drained soil. Hardy to at least -25°C. Plant 2 trees for cross pollination. We have grafted and seedling trees. Note that seedling trees will not be identical to the mother tree so there may be variation in the nut shape and size.
