(Carya cordiformis) Deciduous. Zones 4-9.

Bitternut Hickory is a majestic giant that can live up to 200 years! Plant it now and future generations will enjoy sitting in its shade and foraging for nuts.   

As the Bitternut Hickory matures, its smooth gray and green bark becomes beautifully textured in a loose diamond pattern - a striking presence year-round. The greenish yellow Spring flowers of the Bitternut give way to oval-rounded nuts, encased in a thick green husk that splits when ripe. Bitternuts are not edible - they are much too bitter for humans and most wildlife. 

Cross-pollination generally produces a more abundant crop of better quality nuts so it's best to plant two trees. It can take 8-10 years for trees to begin producing.

Hickory wood is widely used to cure and smoke meats. It is extremely strong and makes heirloom quality tool handles, ladders, and furniture. 

** Please note that all members of the Juglans family (Butternuts, walnuts, heartnuts, etc.) create a protective substance in their roots called Juglone. This can kill certain other plant species within the root zone. Juglone from Hickories and Pecans is very mild.
