Sedum acre

L.

Crassulaceae


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[

The plant is harvested from the wild for local use as a food and a medicine, and also for use in commercial skin conditioners. It is grown commercially for use in 'green roof' systems in order to insulate buildings, provide wildlife habitats and moderate the environment, and is also sometimes grown as an ornamental in gardens, where it can be used as a ground cover.
Sedum acre can be invasive and spread indefinitely, swamping out less vigorous neighbours[

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[

Propagation

Seed - surface sow in spring in well-drained soil in a sunny position in a greenhouse. Do not allow the soil to dry out. It can also be sown in the autumn in a cold frame, some seed germinates immediately whilst others germinate in the spring. Prick out the seedlings into individual pots when they are large enough to handle. If sufficient growth is made, it is possible to plant them out during the summer, otherwise keep them in a cold-frame or greenhouse for their first winter and plant them out in early summer of the following year[

Division is very easy and can be carried out at almost any time in the growing season, though is probably best done in spring or early summer. Larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.
