Description

This

compound, usually with 8 to 15 pairs of narrow, oblong leaflets.[4] Soft white hairs on the leaves and the stem give them a silvery, or hoary, appearance.[6]

The flowers look similar to other flowers in the pea family and are bi-colored, with a pale yellow or cream upper petal (the standard), and pink petals on the bottom (the keel and wings).[5] The flowers are grouped into clusters at the top of the stems and bloom from May to August. The seed pods that form after the flowers bloom are small, approximately 5 centimetres (2 in) long.[4]

The roots are long and stringy, which is probably the source of the common names catgut and devil's shoestrings.[5]

Distribution and habitat

This plant prefers acidic soils, in part to full sun.

Midwest, New England and southeastern United States.[8] Not easy to propagate because of the relationship it has with the acid soil it needs,[9] this plant can be found in sand savannas, open woods and glades, prairies and rocky soils.[4]

Toxicity

All tissues of this plant are toxic (containing rotenone), and should not be eaten by people or livestock. Crushed stems were previously used as a fish poison.[10]

Conservation

While ranked as secure rangewide by

black oak savanna and black oak woodland in Ontario.[11]
