They are shrubs or small slow-growing evergreen trees that reach 6 meters (19.68 feet) in height and 3 meters (9.84 feet) in width. The leathery, fleshy leaves are bright green or burgundy in color. The flowers are white or pink and have a jasmine scent. They bloom in late winter. The toxic fruits are black when ripe. Dune poison-bush is used to form hedges, barriers and screens, as isolated specimens and in pots for patios and terraces. They are ideal for Mediterranean coastal gardens. Acokanthera oblongifolia grows in full sun and light shade exposures. Resists light and occasional frosts. The soil can be normal, well-drained garden soil with coarse sand and containing abundant organic matter. Water regularly, waiting for the substrate to dry; they resist drought well when they are settled. Young plants need more watering during the first 2 years after planting. Fertilize with manure or compost in autumn. Prune lightly after flowering to maintain a compact appearance. African wintersweet is a plant resistant to the usual pests and diseases. Poison arrow is propagated from seeds sown in spring or fall and by cuttings in summer. |
