In terms of bloom period and easy care, grevilleas are reminiscent of our own Ceanothus or California lilac shrubs, which will soon be flowering in white and in all shades of blue.
TIP OF THE WEEK: Grevillea robusta, or silky oak, is the one tree species in the grevillea group, and it blooms, uncharacteristically, with orange-yellow flower combs in late winter.
With some notable exceptions, grevilleas generally grow to a substantial size, which makes them unsuitable for small gardens (although pruning can restrain some of them).
Unless otherwise noted, plant grevilleas in full sun and well-drained soil that's low in organic matter.
In fact, "most grevilleas won't tolerate high levels of phosphorus and alkalinity," says Steve Brigham of Buena Creek Gardens in San Marcos, California.
To restrain the size of grevilleas, prune after flowering.
