The flowers of Crassula fallax grow in small, dense clusters at the top of slender, erect stalks. The flowers have five, pointed, cream coloured or nearly white petals. Flowering happens from late spring to early autumn.
The plant is found on coastal sandy flats and dry slopes of fynbos and succulent Karoo veld, from Swellendam to Clanwilliam. The plant is in 2013 not considered to be threatened (Mustart, et al, 1997; Bond and Goldblatt, 1984).
