The Pigeonpea (Cajan) has green foliage and inconspicuous yellow flowers, with a moderate amount of conspicuous brown fruits or seeds. The greatest bloom is usually observed in the indeterminate, with fruit and seed production starting in the year round and continuing until year round. Leaves are retained year to year. The Pigeonpea (Cajan) has a short life span relative to most other plant species and a moderate growth rate. At maturity, the typical Pigeonpea (Cajan) will reach up to 10 feet high, with a maximum height at 20 years of 10 feet.

The Pigeonpea (Cajan) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by bare root, container, seed. It has a moderate ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 31°F. has high tolerance to drought and restricted water conditions.
