Carya glabra
pignut hickory

Notes:

Taprooted. Deep rooting habit is conditional on good drainage. Not for use near streets, parking lots, driveways, walkways due to hazard from nuts. More refined foliage than most hickories.

Said to be the fastest-growing of the hickories; however, NCSU, USDA, JerseyYards.org, and Odenwald/Turner still classify it as slow, soundly outnumbering Cal Poly. Dirr & Warren claim 1-2'/year.

NCSU, JerseyYards.org, and Cal Poly all assert clay tolerance, outnumbering USDA.

Hickories produce juglone, but not on the level of black walnut (Juglans nigra).

Native to hillsides and ridges with well-drained soil.
