Grevillea Grevillea   Proteaceae

Grevillea, Grevillea


Grevillea, Grevillea	This genus numbers some 250 species of evergreen shrubs and trees in the protea family. Extremely variable in habit, foliage and flowers, most grevilleas are native to Australia with a few species from New Caledonia and Papua New Guinea. The small flowers are mostly densely crowded into heads or spikes, their most conspicuous feature being the long styles which are at first bent over like a hairpin and then straighten out. Many are adaptable and easy to grow, with a long flowering period and are popular with nectar-seeking birds. The leaves are commonly deeply divided and may be very decorative in their own right, the foliage of some species being grown for cutting. In the last several decades hundreds of hybrid grevillea cultivars have been bred, nearly all in Australia, and many are extremely floriferous. Some of the most beautiful species are low growing or prostrate; these may be planted in a rock garden, as ground cover or in containers.
Hardiness zone from 7 To 12 .Plant Height From approx. 60 To 3000 cm
Flowering colors: Cream, Crimson, Green, Mauve, Orange, Pink, Red, Scarlet, White, Yellow
Garden type: Seaside,Cultivation: Moderately frost hardy to frost tender, grevilleas do best in well-drained, slightly dry, neutral to acid soil in full sun. Strong roots develop early and it is important not to disturb these when planting out. Pruning of the shrubby species and cultivars is recommended immediately after flowering to promote healthy new growth and a compact habit. They are generally pest free although scale insects and leaf spot may pose a problem. Propagate from seed in spring, from cuttings in late summer, or by grafting for some of the species most prone to root-rot.
