|
The genus Grevillea, family Proteaceae, comprises 400-500 species of shrubs and trees native to Australia and Papua New Guinea. Some species are: Grevillea rosmarinifolia, Grevillea lanigera, Grevillea juniperina, Grevillea johnsonii, Grevillea Golden Yu-Lo, Grevillea Clearview David, Grevillea brachystachya, Grevillea robusta, Grevillea alpina, Grevillea sulphurea, Grevillea thyrsoides, Grevillea crithmifolia, Grevillea olivacea. Common name: Rosemary grevillea. This species is native to New South Wales and Victoria, Australia. They are rounded shrubs that reach 3 meters (9.84 feet) in height. The leaves are linear and alternate; they resemble the leaves of the Rosmarinus. The curious red flowers appear in clusters. They bloom from spring to summer but can do so throughout the year. They are used to form bushy groups, as isolated specimens and in pots for patios and terraces. Grevillea rosmarinifolia needs full sun or light shade exposure and warm temperatures. They do not resist frost. The soil must be well drained and contain organic matter such as leaf mulch or peat. Water regularly, waiting for the substrate to dry; they resist several days of drought. Fertilize in autumn with humus or compost. They do not need pruning. They are quite resistant plants to pests and diseases. They propagate by seeds sown in spring in a glass-protected seedbed. |
