Grevillea x semperflorens is a hybrid whose parents are said to be G. thelemanniana and a yellow-flowered form of G. juniperina.

The hybrid was found in a Plymouth (UK) garden in the late 1920’s.

Grevillea x semperflorens is an upright shrub that, in our garden, reaches a height of two metres. The narrow leaves may be linear or divided into segments crowned with a sharp point. Orange-red flowers are held in pendulous racemes.

The plants have proved to be hardy, very free flowering; frost resistant and once established have very low water requirements. An occasional light pruning is appreciated.

Propagation must be from cuttings to preserve the hybrid’s characteristics.

Grevillea x semperflorens was probably one of the first named grevillea hybrids.
