Sedum reflexum forma cristatum is the cristate form of the Blue or Reflexed Stonecrop and has stems that are flattened and elongated into bizarre shapes with distorted crests. This form of fasciation creates plants that are unique and ideal for nurturing into cherished specimens. Occasionally non-crested stems can form on the same plant and these can be either cut off to preserve the strange beauty or just left on.

Like its non-crested type species, Sedum reflexum forma cristatum is an easy plant to cultivate and likes a free-draining substrate and sun but will tolerate both wet roots and shade and - if grown outdoors - sub-zero temperatures. It is however such a special plant that it is best appreciated indoors, ideally in a terra-cotta or ceramic container where its otherworldly beauty can be observed at close quarters.
