Carya cordiformis


Bitternut hickory grows on rich, dry uplands in the acid soils of east Texas and also in low moist areas near the edges of swamps and streams. The bark is a silvery reddish brown, thin, and sometimes broken up into platelets, but never shaggy. The bright sulfur-yellow winter buds distinguish it from other Carya species. The nuts are so bitter that they are hardly eaten by wildlife.
