Description and Ethnobotany

Growth Form It forms a cluster of erect stems that typically grow up to 15 cm tall but sometimes up to 20 cm tall.
Foliage Triangular, fleshy leaves are densely and compactly arranged around the stem in pairs with adjacent pairs rotated 90 degrees from one another. Light green leaves have dark purple edges and small spots.
Stems Stems mainly erect but some may lean horizontally before becoming vertical at the tips.
Flowers Small, white, star-shaped flowers are composed of 5 triangular petals.
Associated Fauna It is prone to attack by mealy bugs and snails.
Taxonomy This cultivar was produced by crossing Crassula rupestris subsp. marnieriana with Crassula rupestris subsp. rupestris.
Cultivation Plant in well-drained, loose media containing some organic matter. Thoroughly saturate the media with water, drain excess water and do not re-water until the media is completely dry. Leaves develop red edges when the plant is under stress. It is considered easy-to-grow and best grown outdoors with protection from hot afternoon sun. To propagate, pull entire leaves or offsets, allow the cut end to form a callous over a few days and plant in well-drained soil.
