Tephrosia virginiana, also known as goat-rue, goat's rue, [3] catgut, [3] rabbit pea, [3] Virginia tephrosia, [3] hoary pea, [4] and devil's shoestring [5] is a perennial dicot in family Fabaceae. The plant is native to central and eastern North America.
This subshrub is low and bushy, growing to 60 centimetres (2 ft), but more often shorter. Its leaves are alternate and 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]
This plant prefers acidic soils, in part to full sun. [7] It grows throughout the 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]
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]
While ranked as secure rangewide by NatureServe, [1] T. virginiana has been listed as an endangered species in Canada under Schedule 1 of the Species at Risk Act since 2003. [11] Only two populations exist within black oak savanna and black oak woodland in Ontario. [11]
