Crassula deceptor occurs in the western parts of South Africa, the Richtersveld, Namaqualand and in the Knersvlakte. It used to be called C. tecta and C. deceptrix respectively. The square stems of densely stacked leaves branch at the base to form clumps.
The leaves are whitish, powdery with green spots showing through, but there are colour variations with greener and redder leaves. The upper surface of the leaf is characteristically demarkated by a distinct line. Branched cymes of small pink, scented flowers appear whenever conditions are favourable.
