Associations

Descriptions

The star-shaped flowers attract bees, butterflies, and other pollinators. Leaves are browsed by cattle, goats, and game. Fruits are eaten by birds, monkeys, and small mammals, aiding seed dispersal. The plant supports butterfly larvae, such as the rufous-winged elfin and buff-tipped skipper, and provides shelter and food for a range of wildlife. Dense growth helps with soil stabilization and erosion control.

Flowers and fruits

Mauve to purple, star-shaped flowers pollinated by insects; four-lobed, edible fruits relished by birds and mammals.

Birds

Fruits are eaten by bulbuls, mousebirds, barbets, and other frugivorous birds; dense foliage offers nesting sites.

By Seeds:

Sow fresh seeds in spring; soak in warm water overnight to improve germination; germinates readily in warm, moist conditions.

By Cuttings:

Semi-hardwood cuttings root well with hormone treatment; keep moist and shaded until rooted.

Traditional Uses

Fruits eaten fresh or used for making jams and fermented drinks; bark and roots used medicinally for digestive and respiratory ailments. Bark and roots used as shampoo.
Not a primary fodder species; leaves occasionally browsed by livestock and game.
Non-toxic.
Excellent for hedges, erosion control, and restoration of disturbed or degraded sites.
