Pigeon Pea (Cajanus cajun): A Cover Crop for Hot and Humid Areas
By: Justin Duncan Published December 2021
Pigeon pea is an upright trifoliate herb. Some varieties, if allowed, can become a small tree. It is weakly perennial but is most often used as an annual, although it can live three to five years, with the most productive seed bearing occurring in the first two years. In south Texas, many plants can survive over the winter to continue producing into their second year.
