Care of the shrub Grewia occidentalis or Cross-berry |
The genus Grewia, family Malvaceae, comprises 300 species of shrubs and trees native to Africa, Madagascar, Asia and South America. Some species are: Grewia occidentalis, Grewia lasiocarpa, Grewia tenax, Grewia asiatica, Grewia tiliaefolia, Grewia orientalis. Common names: Cross-berry, Four-corner. This species is native to South Africa, Zimbabwe and Mozambique. They are shrubs or evergreen trees that reach 3 meters (9.84 feet) in height. The leaves are glossy dark green, elliptical in shape and with a serrated edge. The attractive flowers are star-shaped with purple, lavender-pink or lilac petals. They bloom during the summer and then produce four-lobed fruits, hence their English name "Four corners." Cross-berry is used to form screens, as isolated specimens and next to walls and buildings because the roots are not aggressive. It attracts butterflies and birds. Grewia occidentalis can grow in full sun, semi-shade or shade exposures. It resists light and occasional frosts. Four-corner prefers a garden soil drained with coarse sand and containing organic matter. Cross-berry resists drought well; water moderately waiting for the substrate to dry. Grewia occidentalis appreciates a late winter fertilization with manure or compost. Four-corner does not need pruning. Grewia occidentalis is a quite resistant plant to the usual pests and diseases; sometimes it can be attacked by caterpillars. Cross-berry propagates by seeds sown in spring. |
