Crassula fascicularis is a small, few-branched and erect shrublet that grows to heights around 40 cm.
The stems are topped by rounded 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. Old flowers turn red. The flower's allure mainly lies in the five delicate, recurving petals.
The species distribution in the west of the Western Cape ranges from Vanrhynsdorp and the Gifberg to Bredasdorp and the Langeberg Mountains.
The habitat is fynbos slopes among sandstone or gravel. The species is not considered threatened in habitat early in the twenty first century.
The plant deserves consideration from especially Cape gardeners (Smith, et al, 2017; Manning 2007; iNaturalist; http://redlist.sanbi.org).
