Leatherwood
Growth Habit
ShrubBiocultural Value
Several Native American groups used the tough, pliant bark as a fastener or twisted it into cordage. Medicinally, it was employed as a kidney/urinary medicine, cathartic, emetic, and internal analgesic.
Poisonous
The bark, fruit, and roots of this plant are toxic. Some people have allergic reactions from contact with the bark.
Wildlife Value
Leatherwood's yellow, petal-less flowers attract a variety of small to medium-sized bes in early spring, including carpenter bees (Ceratina spp.), cuckoo bees (Nomada cuneata), mason bees (Osmia lignaria), Halictid bees (Lasioglossum spp.), plasterer bees (Colletes inaequalis), and Andrenid bees (Andrena rugosa). Mourning cloak butterflies (Nymphalis antiopa) also visit the flowers seeking nectar. A number of insects feed on the bark and foliage, including the leaf-mining larva of a specialist moth, Leucanthiza dircella. Most mammalian herbivores avoid eating the toxic foliage.
