About

This small to medium-sized tree is distinctive for its often gnarled trunk and smooth, light grey bark, which frequently develops characteristic knobs or bosses. It produces attractive clusters of small white flowers, followed by edible, small orange-red fruits that are a favourite of local birds.

Where it works in Kilifi

Ideal for full sun to partial shade locations, this adaptable tree thrives in well-drained soils along the Kilifi coast. It can be used as an attractive specimen, a light shade tree, or for adding biodiversity to restoration projects.

Growing notes

Knobwood exhibits a moderate growth rate and is remarkably drought-tolerant once established, requiring minimal watering. It is hardy and well-suited to coastal conditions, generally requiring little special care.
