Description and Ethnobotany
| Growth Form | Herbaceous succulent trailing sub-shrub. |
|---|---|
| Foliage | Leaves powdery-green to bluish-green due to whitish bloom, spindle-shaped, recurved with pointed tip, fleshy and turgid, 20mm long by 8mm wide, closely-whorled around stem. |
| Stems | Fleshy, long and pendulous stems can reach up to 1.2m long. |
| Flowers | Small but showy, with pink petals, yellow anthers, fleshy lighter pink sepals and slender pedicels, secrete abundant nectar, borne in few-flowered inflorescences at ends of stems, rarely produced and only in mature specimens with stems of at least 25cm length. |
| Fruit | Not observed before. |
| Similar | Resembles Sedum burrito (Baby Burro's Tail), but latter is of smaller form, with straight leaves that are shorter and blunt-tipped, as well as smaller flowers. |
| Cultivation | In Singapore, this species requires air conditioning to survive. It likes being potbound in well-drained media that is allowed to dry between watering. Avoid shifting plant too much or placing in high-traffic area, as leaves detach easily from stems when disturbed, and when heavy stems cut into edge of container. Wrap container's edge with split water-hose to protect stems from damage. May be affected by mealybugs -- remove by wiping or spraying with diluted water-detergent solution. Easily propagated by leaf cuttings, or stem cuttings -- remove leaves from base and allow cut end to dry for 1-2 days before inserting into moist sand or cactus soil mix. Plantlets emerge in a few days. |
| Etymology | Genus epithet 'Sedum' derived from Latin word for 'sit', an allusion to how some species of this genus attach themselves to rocks and walls. Species epithet 'morganianum' named by American botanist Eric Walther (1892-1959) in honour of Californian plant hobbyist and expert grower Dr Meredith Morgan, who in 1938 was the first person to get the plant to bloom outside of Mexico. The flowers enabled Walther to identify and describe the species, 3 years after he discovered cultivated specimens growing in tin cans hung from walls in a Mexican nursery. Species is a frequent escapee, hence actual habitat is unknown but thought to be in southern Mexico. |
