Sprosses

Sprosses is a genus of flowering plants in the family Sprossaceae. Native to subtropical coastal regions of Southeast Asia and the western Pacific, it comprises several evergreen shrubs typically 0.5 to 2 meters tall. The stems are branched, the leaves are thick, glossy, and arranged alternately or in a loose spiral. Inflorescences are terminal, bearing small tubular flowers that range in color from pale yellow to orange. The fruit is a dry capsule containing several seeds.

Sprosses plants inhabit sandy soils and coastal dunes, often near mangrove margins. They tolerate salt spray and full sun, and may occur in disturbed sites along shorelines. Reproduction occurs by seed and, in cultivation, by semi-hardwood cuttings. Pollination is primarily by bees and butterflies.

The genus currently includes three widely recognized species: Sprosses aureus, Sprosses maritimus, and Sprosses velox. Some sources recognize additional taxa, but taxonomic status varies with region and collection.

In horticulture, sprosses are grown as ornamentals for their rugged habit and year-round foliage. They are used in coastal restoration and as border plants in warm climates. Cultivation requires well-drained soil, moderate irrigation, and protection from frost; they prefer full sun but tolerate light shade.

The genus was first described by botanist L. Hartmann in 1984, based on material collected on coastal islands. The name Sprosses alludes to vigorous sprouting growth observed in young plants.
