Grevillea crithmifolia has two forms. One is a compact two metre tall shrub. The other is a dense ground cover with a spread of at least two metres. The groundcover form is the one most favoured by gardeners.
Light green leaves are divided at the end into three narrow segments.
In spring plants are covered with dense clusters of white or pink flowers. Honeyeaters are attracted to the flowers.
Grevillea crithmifolia is found in the southwest of Western Australia.
Prune lightly after flowering to maintain dense foliage. A well-grown, ground covering form of Grevillea crithmifolia will form a dense, weed-suppressing carpet.
Propagate from cuttings which may be slow to produce roots.
The species name refers the similarity of the leaves to those of the genus Crithmum, Rock Samphire.
