Cussonia thyrsiflora


Common names: Cape coast cabbage tree (Eng.); Kaapse kuskiepersol (Afr.)

Flower heads in bud

This evergreen shrub or small tree is an ideal specimen to include in coastal gardens, as it is very hardy and well adapted to dry coastal scrub. It bears yellow-green flowers, which are followed by fleshy black fruit.

Open flowers

Cussonia thyrsiflora is a dense, spreading shrub and could be considered as a small tree of 2-5 m in height and equal spread. As a tree it can form a full canopy if pruned carefully.

C.thyrsifoliaLeaves are composed of 6-8 palmate (arranged like a fan), glossy leaflets, 50-80 x 20-40 mm. Leaves are usually arranged at the ends of branches. The flowers are arranged in a spike of yellow-green flowers also at the ends of branches between November and January. Spikes of purple to black berries each about 4 mm in diameter, bear the seed from April to June. The flowers and buds appear to be waxy. The branches of this species have many leaf scars and are grey in colour and rather corky.

Currently this species is not listed as a threatened plant, however, with ever increasing development along the southern and southeast coast of South Africa, it could make the rare and endangered list in future.

Distribution and Habitat
Cussonia thyrsiflora is found in dry coastal thicket growing amongst species such as, Sideroxylon inerme (milkwood), Chrysanthemoides monilifera (bietoubos), Rhus crenata (dune crow-berry), Metalasia muricata (blombos) and many other common coastal shrubs.

It is widespread from the Cape Peninsula to Port Elizabeth along the southwestern, southern and southeast coastline of South Africa. It is well adapted to strong coastal winds and poor dune soils.

Uses and cultural aspects
The cabbage trees' roots, being tuberous and fleshy, especially those of Cussonia paniculata, C. spicata and C. thyrsiflora, have been known to be peeled and eaten as a source of food and water by the San people.

Growing in the garden

Growing Cussonia thyrsiflora

The best way to propagate this plant is by sowing ripe seed that forms on the tree by June. This should be sown in a well-drained soil and covered with a thin layer of soil. Seedlings germinate relatively easily and should be planted out into a larger container as soon as they have developed four to six leaves.

The young plant requires a well-drained soil and should be planted in full sun as an accent/focal point or as a companion plant to grow with other coastal shrubs. As this is a coastal plant, it may not be frost hardy in inland gardens.
