They are small, stiff shrubs with small leaves and tubular flowers. The fruit is a greenish-red berry with distinct ribs. S.laeta is a small shrub up to about half a metre in height. It has stiff stems with lance-shaped or triangular leaves up to 25mm long. The flowers are usually greenish-yellow or occasionally reddish with curled lobes and prominent stamens.
Flowers appear from autumn to spring and are frequented by honey-eating birds.
S.laeta is not often seen in cultivation except in the gardens of enthusiasts. The species should be given a moist, well drained position, preferably in semi shade. It is a very attractive plant for a container. Propagation is usually by cuttings of firm current season's growth and improved results have been reported when a root-promoting hormone is used. The species can be grown from seed but this is not readily available.
