The genus Sedum (sensu lato) is a large and diverse grouping of species. Various molecular studies since 1995 have indicated that many of these species would be better placed within segregate genera - a treatment that is not universally recognized. We have chosen to follow the Flora of China[] and Flora of N. America[] in recognizing these new genera. When the nomenclatural, biogeographic, and morphological data has become available for many other groupings within Sedum, it is likely that more new genera will be established - to date we have transferred a number of species to the genera Hylotelephium. Phedimus and Rhodeola[].

Common Name:

General Information

Sedum drymarioides is an annual plant with a single, much-branched stem; it can grow 7 - 25cm tall[].
The plant is harvested from the wild for local use as a medicine.

Known Hazards

All species in the genus Sedum (including the closely allied genera such as Hylotelephium and Phedimus) have more or less edible leaves and young flowering stems, though they are not always totally desireable with several species having bitter, acrid or peppery flavours!
However, the plants contain various alkaloids including sedine and sedamine. These can sometimes cause gastric upsets, usually of a mild nature[]. This is most likely to happen with species that have yellow flowers, though eating large quantities of any species could be problematic[, ].

Cultivation Details

Most Sedum species will grow best if given a moist, but well-drained, fairly fertile soil in a sunny position[]. Many of the species will do well in quite dry positions, in poor soils and in light shade - see notes on the plant's habitat for ideas about this[]. Most species are somewhat to very drought tolerant[].
This species has white flowers[]. All members of this genus are said to have edible leaves, though those species that have yellow flowers can cause stomach upsets if they are eaten in quantity[, ].
Species in this genus are often specially targeted by slugs[].
Plants in this genus seem to be immune to the predations of rabbits[].

Edible Uses

We have no specific mention of edibility for this species but, in general, the leaves of all members of this genus are edible, though not always very desirable[, ]. Some caution should be employed however, particularly if the plant has yellow flowers - see the notes above on toxicity[].

Medicinal

The plant is used medicinally[]. No more information is given, but Sedum species (including Hylotelephium and Phedimus) generally contain various medicinally active compounds including alkaloids, tannins, cyanogenic compounds and, in particular, a range of flavanoids with anti-inflammatory and pain relieving properties. Many Sedum species are used medicinally to treat pain and inflammation - in addition a poultice made from the crushed, succulent leaves and young stems can be applied topically to cuts, wounds, burns and various skin disorders[].

Other Uses

None known

Propagation

Seed - surface sow in early spring in well-drained soil in a sunny position in a greenhouse. Do not allow the soil to dry out. Prick out the seedlings into individual pots when they are large enough to handle and plant out in late spring.
