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.

Partridge Pea (Cassia chamaecrista)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.

Planting season: scarified seed: Spring; unscarified seed: Fall 

*Special considerations for spring planting: seed germination can be improved with mechanical scarification. Seed needs to be inoculated with Rhizobium (EL-cowpea type) for nitrogen fixation to occur. Germination of scarified seed generally occurs within 2 weeks after planting provided adequate soil moisture and temperature conditions are met.
