Description and Ethnobotany
| Growth Form | Herbaceous succulent sub-shrub, 15 - 20cm in height. |
|---|---|
| Foliage | Fleshy oval leaves, glossy green-red, arranged spirally around fleshy stems. |
| Flowers | Yellow, borne in inflorescences, seldom produced and not observed in Singapore. |
| Similar | Of horticultural hybrid origin and found only in cultivation, thought to be Sedum stahlii × Sedum pachyphyllum. Previously confused with Sedum guatemalense, an epiphytic species. Chimeric cultivar 'Aurora' has chlorophyll-deficient leaf epidermis and completely pearl-pink colouration. |
| Cultivation | Provide full sun for more intense cherry-red colouration, leaves tend to turn glaucous green and plant becomes leggy when not exposed to sufficient light. Use well-drained media and allow to dry between each watering. Prefers neutral to slightly alkaline media, acidic media can lengthen internodes and make plant leggy. Thrives on neglect. Propagate by leaf cuttings or stem cuttings -- allow cut end to callous before planting in moist porous media. |
| Etymology | Genus epithet 'Sedum' derived from Latin verb for 'sit', a reference to how some species in this genus attach themselves to rocks and walls. Species epithet 'rubrotinctum' means 'red-dyed', describing how the leaves turn red under full sun. |
