Drosanthemum tuberculiferum is a succulent shrublet with erect and spreading branched stems. The specific name suggests the water-filled surface cells that characterise the genus. This earned these plants the common name of dew-flowers. The cylindrical succulent leaves grow in oblique finger-like pairs with irregular slight curvature. They are grey-green to pale yellow-green.
The flowers are borne in spring on long slender stalks just above the leaves; blooms are prolific after rain. The flowers are small with delicate, shiny petals. There is an ample central brush of white-anthered stamens around the narrowly paddle-shaped petals. As this brush is spreading widely, it can be accepted that there are no staminodes, which are usually associated with a cone-like structure in the centre of the flower (Smith, et al, 1998; www.stridvall.se).
