Tiny yellow flowers appear in profusion on the upper stem parts of Crassula muscosa during spring and summer. The flowers measure no more than 2 mm in diameter. They are star-shaped and grow in leaf axils.
The plant is associated with much variability: four variations are recognised, some of them growing side by side in the same areas (like in the Little Karoo).
General plant appearance has been likened to undersea coral. The species name of muscosa means moss-like (www.smgrowers.com; Smith, et al, 1997; Vlok and Schutte-Vlok, 2010; Bond and Goldblatt, 1984).
