Partridge Pea, Chamaecrista fasciculata, is a slender-stemmed, 1-3 ft. annual with pinnately-compound leaves bearing many small, yellow-green leaflets which fold together when touched. Its large, showy, yellow flowers arise from leaf axils. Each flower is marked with red and is followed by a narrow pod. This is a plant adapted to harsh dry soils and strong sun exposure. It grows and blooms spring to fall and is attractive to pollinators including Bumble Bees and sulfur butterflies, which also use the plant as a larval plant. The list includes Cloudless, Orange, and Yellow Sulfur butterflies, Gray Hairstreak, Little Yellow, and Ceraunus Blue butterflies. Birds use the seed.
