Native to eastern North America.
Nuts are bitter and squirrels tend to avoid them. Serves as a primary host for some magnificent moths. Larval Host: Luna, funeral dagger, and giant regal. Attracts birds and butterflies.
A slender shade tree, bitter-nut hickory is one of the largest hickories, growing 50-100 ft. tall. Bitter-nut hickory typically develops several primary ascending limbs, forming an arched shape. The deciduous tree produces long, graceful catkins and large, hard-shelled nuts. The pinnately-compound leaves attain a bright, clear yellow early in the fall. It holds its fall foliage longer than other hickories.
This is the most rapid growing of all hickory trees. It is difficult to transplant because of a large taproot, but perhaps less so than other hickories.
