Crassula fascicularis is a small, branched shrublet that grows several erect stems, topped by clusters of white, cream or yellow-green spring flowers. Each flower has a long tube enveloped halfway up its length in a pale green or pinkish calyx.
The flower's allure mainly lies in the five delicate, recurving petals. The plant deserves a thought from especially Cape gardeners.
The species distribution in the Western Cape ranges from Vanrhynsdorp to Bredasdorp. Its habitat is fynbos slopes among sandstone (Manning 2007).
