This annual is a fun plant and low growing 1' tall and up to 15' wide, the wild sensitive-pea gets its common name from the fact that the leaflets fold together when touched with a finger. Also known as sensitive cassia, sensitive or small partridge pea. It likes to grow in man-made or disturbed habitats, grassland, meadows, fields and occasionally wetlands in full sun. Sandy soil and once established, requires little water as it likes it on the dryer side. The yellow flowers are a nice nectar source when the plant is blooming and the plant is a food source/ host plant for Cloudless Sulphur, Sleepy Orange, and Little Yellow caterpillars.
