Grevillea banksii 'Forsteri', known as the Banks' Grevillea or Red Silky Oak, is one of the most widely cultivated of all grevilleas and a parent of an increasing number of hybrids. Typically it is a large, spreading shrub to around 3 metres but smaller if pot grown. The silvery-green, much divided foliage complements the red flowers that are produced in large clusters at the ends of branches. Flowering usually occurs in spring although it may flower for much of the year. G.banksii is a hardy plant for warm climates where it performs best in reasonably well-drained soils in full sun. Plants can tolerate light frosts but best under frost free glass in the UK for the winter.
