Cussonia paniculata Eckl. & Zeyh.

Family: Araliaceae
Common names:
Mountain cabbage tree, bergkiepersol (Afr.), Umsenge (X, Sw) Umsengembuzi (Z)

Mature Cussonia paniculata

This evergreen tree makes a beautiful focal point in a garden as it has an unusual shape, interesting gnarled bark and stunning, large, grey-green leaves. Plants show up especially well in a layout where rocks are used. Gardeners growing indigenous South African plants favour them greatly for their unique appearance.

This is a short, thick-set tree, rarely exceeding 5 m in height. It is sparsely branched with grey, longitudinal fissured, thick and corky bark. The stem is thick and squat. This plant is considered a pachycaul succulent on the basis of its swollen stem base or tuber which forms early in plants grown from seed. Roots are also thick and swollen. The tree is slow growing.

Cussonia paniculata

The large, digitately compound, cabbage blue leaves are one of its most distinctive features. The leaf colour is in some part due to the thick waxy layers on the leaves, which may help protect them against severe frosts. The leaves are composed of 7-9, but sometimes up to 13 leaflets, springing from the end of a long stalk. The leaflets are up to 30 cm in length and the overall leaf can reach 60 cm. The leaflets of some forms are deeply lobed. New leaves are brighter green and emerge in a spring flush at the ends of branches.

There are two subspecies of Cussonia paniculata. The smaller mountain cabbage tree C. paniculata subsp. paniculata has leaflets without lobes and has a limited distribution in Eastern Cape. C. paniculata subsp. sinuata forms a larger tree with deeply lobed leaves and is more widespread. This is the form more commonly found in cultivation.

Unlobed leaves of C.paniculata subsp.paniculata

From January to April these trees bear small, green, stalked flowers; in short dense spikes, making up a large, branched inflorescence at the end of the trunk or branches. Flowers are followed by fleshy and purple-maroon fruits, which mature in May to June.

Cussonia paniculata occurs inland at altitudes up to 2 100 m. It is often found in rocky places from the mountains of the Karoo and Eastern Cape through KwaZulu-Natal and Free State into Gauteng and further north. It grows in crevices filled with natural organic humus and compost. It is commonly found near Johannesburg and Pretoria. It is frost-tolerant and drought resistant.

Derivation of name and historical aspects
The name Cussonia was given by Carl Peter Thunberg to commemorate the French botanist Pierre Cusson (1727-1783). The specific name refers to the panicle or branched inflorescence. It is believed that the name 'kiepersol' comes from the Portuguese (Quinta-sol) or Indian (Kitty-sol), words for a parasol or sunshade. The genus has about 25 species of which about eight occur in South Africa. The remainder are found throughout tropical and southern Africa, Madagascar and the Comoro Islands.

The flowers are pollinated by an enormous variety of insects that have wings e.g. bees, wasps, flies. When they are in full flower it sounds like a beehive. The flies and insects are attracted by the flowers' smelly nectar. The flowers may have lots of pollen too. The seed are not as easily parasitized by pests as Acacia and Rhus species. The birds feed on the ripened, black seed.

Use and cultural aspects
The wood is soft and light and was used for the brake-blocks of wagons. The leaves provide good fodder for stock and the Zulu name refers to this tree as goats' food. The thick root can be peeled and eaten raw as food or as a source of water (Van Wyk & Gericke 2000). Recent research (Tetyana et al. 2002) sets out to investigate the traditional medical uses of Cussonia and Schefflera to treat infections, inflammation and malaria.

Growing Cussonia paniculata

The best method of propagation is by means of seed harvested from fresh ripe fruits. Detailed instructions on propagation are found in Oliver (1987). Sow seed as soon as possible as it loses much of its viability within 3 months. However, seed sown in summer months will germinate faster (in about 4 weeks) than seed sown in winter (7 weeks to germination). Make sure seed trays are at least 15 cm in depth to allow the small tubers to form. Do not allow seed to become waterlogged or dry out. Keep seed and seedlings in a semi-shaded area. Seedlings can be transplanted at about 4 months, but be very careful not to damage the fleshy roots when transplanting.

One can grow Cussonia paniculata from a cutting, but this is not advisable because it does not make the proper, fleshy, underground rootstock that it forms when grown from seed.

Tetyana & Van Staden (2001) write about the micropropagation of this species, mentioning the benefits that could be derived from propagating forms with variegated leaves as ornamentals.
