The center for black raspberry production is in the Willamette Valley in Oregon. "Dark raspberry" is a color that resembles the color of a black raspberry. The larvae feed on the leaves of "Rubus" species (including black raspberry and purple-flowering raspberry). Yellow-fruited variants of the black raspberry are sometimes grown in home gardens. "Rubus leucodermis" is closely related to the eastern black raspberry "Rubus occidentalis". The shrub layer is dominated by black raspberry ("Rubus occidentalis") and other brambles ("Rubus" sp.). These include black raspberry, wild ginger, maidenhair fern, showy orchis, wild coffee, and numerous others.
