Dune Soapberry (Deinbollia oblongifolia) is a hardy, evergreen to semi-deciduous shrub or small tree that usually grows 1.5 to 5 meters in height, but can sometimes reach up to 9 m. It is often multi-stemmed and is drought and shade-tolerant with a non-aggressive root system. Suitable for shade, containers, and as a formal or informal screening plant. Attracts beneficial insects to the garden and acts as a host plant for the larvae of several butterfly species. The plant has culinary, medicinal uses and is used as a soap substitute.
It has large, compound leaves with leaflets that are dark green, shiny, and crowded at the ends of branches. New growth can be lighter green. Small, white to cream-colored flowers are produced in large, dense, velvety, pyramid-shaped panicles at the tips of branches. Fleshy, round, berry-like fruit (approx. 10 mm in diameter) that are green and velvety when young, turning pale yellow to yellow-orange when ripe.
