I see this species the most growing in draining wet or moist soils in lowlands, but I have seen some in well-drained uphill locations. It is usually the second most common hickory in the North. Native from New England to central MN to east TX to northwest FL. Handsome tree with fantastic texture! Good yellow fall color. Good for wildlife. Slow growing of about 6 to 9"/yr and develops a big taproot like most hickory and lives about 200 years. Sometimes offered for planting by native nurseries in containers. Messy for residential landscapes, but magnificent like oak trees. Can tolerate some soil compaction nearby with new construction. The compound leaves are 6 to 9" long with 7 to 11 relatively more narrow leaflets and it has a more Medium texture, less course than most other hickories, see... read more

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 le... read more

A wonderful tree that wildlife depends on. The nuts are bitter to humans, but deer and other animals use them for winter forage.

Similar to the Pecan in appearance, but it's range is much more widespread,even into southern Canada.

Height 50' to 60', but can get as tall as 100' in the right conditions.
