Partridge-pea, Sensitive partridge pea, Sensitive pea

Fabaceae (Pea Family)


USDA Symbol: chni2

USDA Native Status: L48 (N), HI (I), PR (N), VI (N)

Partridge-pea or sensitive pea is a slender-stemmed annual, up to 1 ft. tall, with pinnately-compound leaves. Each leaf is made up of numerous small, yellow-green leaflets which fold together when touched. The small, yellow flowers hang from short, axillary pedicels.

Like other members of the pea family, this plant requires the presence of microorganisms that inhabit nodules on the plants root system and produce nitrogen compounds necessary for the plants survival.
