Crassula rupestris subsp. Marnieriana is part of the Crassulaceae family and it is native to South Africa where it can be found growing at high altitude in the shallow soil of rock basins on the southern slopes of the Klein Swartberge. Branches have a columnar appearance due to the short internodes between leaves. Flowers are small, tubular and white or pink, emerging from the tips.
Genus name comes from the Latin crassus meaning thick. Rupestris comes from the Latin rupes meaning rock and -estris, as in terrestris meaning terrestrial; of rocky areas, this is in reference to where it grows.
Light: Allow the plant to see the sun for as many hours of the day as possible; Crassula prefer bright light, and become leggy without enough light; south or west window would be ideal.
Water: Crassula are very drought tolerant, allow the potting mix to dry out completely in between watering.
Potting mix: A mix of predominantly non-organic material like clay, pumice or lava grit with a small amount of coco coir. You could also amend our regular potting mix with some horticultural grit.
Fertilising: Feed every few waterings during the growing season. You can dilute fertiliser to half the recommended amount but never add more. It isn’t a heavy feeder.
Temperature: Ideally 21˚C and above.
Humidity: Low humidity; if the humidity is particularly high, good ventilation is key.
Crassula are toxic, keep out of reach of pets and children.
