Dichrostachys cinerea aka Marabou Thorn

Dichrostachys cinerea is a thorny shrub or small tree. Common names include marabou thorn and sickle bush. It belongs to the pea family, Fabaceae. Its native range spans much of tropical Africa. It also grows naturally from India to Indonesia. It lives in grassland, scrub, hedges, and teak forest. The species varies greatly across its wide range. Useful Tropical Plants reports its conservation status as Least Concern.

Plants grow about 3–26 feet (1–8 metres) tall. Some reach 39 feet (12 metres), beyond the usual range. PFAF gives a spread of 26 feet (8 metres). Growth proceeds at a medium rate. The crown is open, and stems may twist together. Sharp spines cover the plant and make handling risky. Sources differ on how long it keeps its leaves. Descriptions range from evergreen to partly or fully deciduous. Root suckers can build broad, dense thickets over time.

Pink and yellow flowers form two-coloured clusters in early summer. Their shape gives rise to the name princess earrings. Bees and bats pollinate the flowers. The plant also draws wildlife to the garden. Fruits are slim pods that turn yellow or brown. Each pod holds about four small black seeds. PFAF lists the fruit, pods, and seeds as edible. These food records do not establish safety for every use. The evidence gives no clear account of chemical toxicity.

This tropical plant grows in sun or light shade. It prefers moist ground but can withstand drought. Clay, loam, and sandy soils can all suit it. Good drainage matters, and poor soil need not prevent growth. It tolerates a wide range of soil acidity. Sources also report tolerance of salty soil. PFAF lists USDA zones 8–12, yet warns against frost. That warning matters when choosing a site in cooler climates.

Gardeners grow it for flowers and its winter branch shape. It also serves as a hedge and supplies fuelwood. Plantings help hold soil and restore damaged ground. The plant fixes nitrogen, and its leaves provide green manure. Traditional medicine uses its bark, roots, and leaves. Those records describe uses, not proof of safe treatment. Strong suckering gives it clear weed potential. Root suckers and root cuttings offer ways to propagate it. Stored seed may suffer insect damage.
