The flowers of Crassula deltoidea grow on fleshy, purplish stalks in a branched inflorescence. Multiple panicles appear at or near stem tips on a mature plant.

Flower colour is creamy white, the base of the five petals red in the photo. The petals form a small cylindrical corolla, held at the base by the five pale calyx lobes that are short and acutely pointed. Yellow or dark anthers can be seen protruding at the top from the corolla mouths in the photo. The flower becomes about 5 mm long.

Some old, bare stems are visible below the leaves, thick with circular ridges around them (Vlok and Schutte-Vlok, 2010; www.plantzafrica.com).
