Annual herb with erect stems to 15 cm long, little branched and mainly from the base. Leaves succulent, lanceolate to 6 mm long and 4 mm wide, slightly but abruptly constricted towards the base; flat to slightly convex above, more or less convex below, green to reddish-brown. Inflorescence in the axils of leaf-like bracts with pale-yellow to red flowers. Flowering between August and November. This variety differs from the other variety found in South Australia by have follicles (fruit capsule) almost cylindrical and slightly laterally compressed, abruptly constricted in the lower third and gradually constricted into a slender style, with a cluster of crustaceous brown tubercles in the lower third but otherwise membranous, whereas Crassula colorata var. colorata has follicles laterally compressed, slightly constricted at the base, gradually constricted into slender styles; smooth, membranous, usually pale. Fruits are small pale brown capsules in clusters along the stems. Seeds are tiny brown ellipsoid seed to 0.4 mm long and 0.2 mm wide, smooth.
Seed collection and propagation
Collect seeds between September and December. Collect whole plants that are drying off, turning red-brown with mature fruit-spikes. These will contain very small brown seeds when rubbed with your fingers. Place the plants in a tray and leave to dry for two weeks. Then rub the plants gently by hand or with a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Be very careful as the seeds are very small. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. Seed viability is usually.
