All forms have silvery-green, much divided foliage and flowers in large clusters at the ends of branches. The flower colour is usually deep red but white forms are also known. Flowering usually occurs in spring although the commonly grown form 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 may be damaged by moderate frosts.
Propagation is best from cuttings although seed is also successful.
