White Crassula rupestris buds clutched by grey-green, pointed sepals in picture, grow on thin, pink-purple pedicels. The pedicels in turn have grown from thicker, pink-purple peduncle branches of the stem-tip inflorescence. Triangular, pointed bracts of similar shape occur at all branching points, increased in size on the lower, bigger branches.
Flower clusters in C. rupestris may also be dense in bud and at anthesis, probably when growth conditions include less moisture (Frandsen, 2017; Smith, et al, 2017; Vlok and Schutte-Vlok, 2015).
