General Description

Gray-green leaves that look like those of a species of Eucalyptus is one reason cobwebby wild indigo is delightful; the others are its yellow flowers and dark seeds. An herbaceous perennial endemic (native only) to Georgia in the southeastern United States, it is a locally (state) and federally endangered wildflower species.

The light green, oval to heart-shaped leaves are covered in silvery gray, making it resemble the florist filler sprigs of an eucalpyt. In early summer, it produces showy bright yellow flowers that look like those of a pea in a slender cluster on stem tips. Butterflies pollinate them and yield the small blackish seeds.

Grow cobwebby wild indigo in full to partial sun in a fertile sandy garden soil that has good drainage. Success with this species is improved if occasionally the plant is reduced by brushfire. As it is illegal to take from the wild, secure seedlings or ethically-harvested seeds to plant in a rock garden or dry meadow. It resents root disturbance and may be slow to establish.
