These are two year old buartblack walnut seedlings that we have specifically bred more cold hardiness into through antifreeze selection, which is described elsewhere on the site. The parent of these seeds are 50% Black Walnut, and 25% and 25% Butternut and Heartnut, respectively. For more information on these particular genetics, see Oikos Tree Crops, Hardy to zone 3.

These trees are 2 ft. and are currently going on their third year. Very well established root system.
