Cussonia spicata (Cabbage-tree) - An unusual and attractive evergreen tree to 30 feet or more with large dissected green leaves held in large heads at the ends of thick soft wood stems that twist and turn in an unusual manner. At the tips of the branches can appear the small greenish-yellow flowers in short spikes in late spring to summer. Plant in full sun to light shade and water regularly, though older plants quite drought tolerant. It is not very hardy and should be planted where temperatures don't get much below freezing for extended periods. Our large tree in the garden withstood overnight temperatures between 24°F and 26°F in the late 1980's but was lost in the cold snap of December 1990 when the nighttime temperatures dipped below 20° F. This species is found over a wide area within moister areas of southern Africa from the southern Cape and eastern parts of South Africa north through Mozambique, Zimbabwe, Zambia into tropical Africa. It is most attractive in its youth as an interesting foliage plant in the ground or in a large pot but it is interesting as a tree as well with snakelike heavy branches that twist about. While certainly not common, Cussonia spicata has long been in cultivation in Santa Barbara and old specimens can be found in gardens and there are some particularly large plants along the biology building at UCSB. Our plants are from seed off an older plant growing in downtown Santa Barbara. The genus was named by Carl Peter Thunberg (1743-1828), the Swedish naturalist often called "the father of South African botany" to honor Pierre (anglicized as Peter) Cusson (1727-1783), a French botanist who specialized in the Apiaceae. The specific epithet is in reference to this plant's spike-like inflorescence. Other names for this plant are the Common Cabbage Tree (distinguishing it from the Mountain Cabbage Tree, Cussonia paniculata, which we also grow) and the Africans name of Kiepersol.
Information displayed on this page about Cussonia spicata is based on the research conducted about it in our library and from reliable online resources. We also note those observations we have made of this plant as it grows in the nursery's garden and in other gardens, as well how crops have performed in our nursery field. We will incorporate comments we receive from others, and welcome to hear from anyone who may have additional information, particularly if they share any cultural information that would aid others in growing it.
