The genus Gymnosporia, family Celastraceae, comprises 100 species of shrubs and trees native to Africa, Madagascar, Asia and the Mediterranean region. Some species are: Gymnosporia buxifolia, Gymnosporia heterophylla, Gymnosporia bachmannii, Gymnosporia tenuispina, Gymnosporia montana. Common names: Common spikethorn, Stinking spike-thorn. This species is native to central Southern Africa. They are small deciduous trees or large shrubs with 10 cm (3.93") long thorns that reach 5 meters (16.4 feet) in height. The leaves are elliptical, with a serrated edge and a bright green color. The flowers appear in abundance on branches that arch elegantly; they are white and showy but they smell bad. They bloom in spring and early summer. They are used to create screens, barriers or hedges and as an isolated specimen (do not plant next to buildings). They are also ideal for bonsai and for Mediterranean coastal gardens. They attract birds and insects. Gymnosporia buxifolia prefers full sun exposure; it can also grow in semi-shade. They resist occasional low intensity frosts. The soil can be a garden substrate with 15% compost and 20% coarse sand. They are low maintenance plants and resistant to drought; water moderately waiting for the substrate to dry. They do not need fertilizers. Prune occasionally after flowering to remove dry branches. They are resistant plants to the usual pests and diseases. They propagate by seeds sown in spring or early summer. |
