Sphaerolobium racemulosum is a leafless, wiry shrub from south-west Western Australia, grown mainly for its red or reddish-orange pea flowers. It is a native species, so it is best treated as a plant for a mild, free-draining site in its climate.

About

Sphaerolobium nudiflorum is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a leafless shrub that typically grows to a height of 0.3–1 m (1 ft 0 in – 3 ft 3 in) and has wiry stems. The flowers are borne in racemes 13–25 mm (0.51–0.98 in) long on short pedicels and are red or reddish-orange, the standard petal twice as long as the sepals. Flowering occurs from July to November and the fruit is an oval to more or less spherical pod about 4 mm (0.16 in) long.

It was first formally described in 1864 by George Bentham in Flora Australiensis. The specific epithet (racemulosum) means "having a small raceme".
