A shade-tolerant cover crop in plantations of cocoa, rubber, coconut and oil palm, now largely replaced by C. pubescens Benth. Used as green manure in sugar cane and in grassland improvement.
Perennial trailing and winding herb, almost glabrous, woody at base. Leaves trifoliolate; leaflets ovate-elliptical, 5-7 cm × 2-13 cm, subglabrous. Inflorescence an axillary raceme with 1-10 flowers, up to 7 cm long; calyx 7-8 mm long; standard white or purple, pubescent, 4-6 cm in diameter. Pod 8-20 cm × 9-16 mm, beak 1-2.5 cm long, 4-ribbed. Seed up to 1 cm long, dark brown to black. C. plumieri nodulates well, but is not adapted to acid soils. Green manure yield is up to 16 t/ha. In Florida (United States), C. plumieri performed better than C. pubescens ; in Belize (Central America) "CF 16-1" was reasonably productive.
