Crassula rubricaulis (Red-stem Crassula) is a succulent plant native to the coastal mountains of the Eastern Cape and Western Cape of South Africa.

[1] This species can be distinguished by its fleshy, succulent leaves, which are a minimum of 2 mm in thickness.

In addition, the leaves are smooth, sessile, egg-shaped (with the narrowest part against the stem), with bright red margins.

It produces large numbers of white, star-shaped flowers in the middle and late Summer.

[3] The Red-stem Crassula occurs around the Riviersonderend and Langeberg mountains in the west, in the coastal rocky mountain shrub around Knysna and as far east as Port Elizabeth.
