This genus comprises evergreen shrubs that resemble members of the myrtle family. They exhibit a compact growth form and produce trumpet-shaped blue flowers. The plants bear purple fruit that is edible but also feature needle-like spines, which should be approached with caution.

Rhaphithamnus spinosus is a semi-hardy evergreen shrub that typically reaches heights of up to 2 meters. This plant features a dense, spreading habit and is characterized by elongated, slender spines along its branches. The leaves are thick and shiny, presenting a leathery texture. In early spring, it produces pale blue, tubular flowers with five lobes, each measuring about 1 cm in length. These blossoms are succeeded by round, fleshy berries that turn a violet-blue hue.
