Chamaecrista fasciculate (Michx.) Greene
Partridge Pea is an annual legume with bright yellow flowers and a excellent food source for a variety of birds.
Partridge Pea is an annual erect legume adapted to a wide geographic area from Maine to Florida, west to South Dakota and Colorado, south through central Texas. It does not compete well in established grasslands but thrives in disturbed areas with an annual rainfall of 15 to 45 inches. Partridge pea grows on a wide range of soils but does best on neutral well drained sites. Partridge pea produces pods with multiple flat black seeds which open up and shatter the seed when mature. It is a prolific seed producer and can become invasive after a few years.
