Description:
Horseflyweed is a bushy perennial with small, yellow, pea-like flowers blooming May-June. The flowers are borne in clusters on tall stems above a mound of gray-green foliage. The flower nectar has special value to native bees and bumblebees. This plant is a host to moth and butterfly larvae (caterpillars), including Frosted Elfin (Callophrys irus), Dusky-winged Butterfly (Thanaos brizo), and Io Moth (Automeris io), and is the only known food source for Wild Indigo Dusky Winged (Erynnis baptisiae) butterfly larvae. Its reputation for protecting horses and mules from horseflies led to its common name, Horseflyweed. Use it in a meadow garden, sunny informal area, or in a butterfly or pollinator garden.
