Description

Sedum is a genus of succulent, herbaceous, evergreen, perennials with fleshy, flat or rounded leaves depending on the species. In general, the plant is upright and spreads along the ground. The genus has over 300 species, though many have been moved to the genus Hylotelephium. The genus name comes from the Latin word sedeo meaning to sit in reference to the habit of many of the sedums species to sit and sprawl over rocks.  

S. acre, or Moss Stonecrop, is a small, hardy, highly salt tolerant, species of Sedum that, like many of its genus, tolerates only occassional foot traffic. The leaves tend to fall off easily; however, the fallen leaves can be used to propagate new plants. Some references describe this plant as mildly toxic if ingested, while others do not. The species is named for its acrid taste. In any event, stems and leaves may be eaten raw when very young and tender. As the stems and leaves age, but before the plants flower, the edible parts may still be eaten if they are briefly cooked. The sap can irritate the skin of some people and the leaves, eaten in quantity, can cause stomach upsets.

In nature, Moss Stonecrop is often found in sunny situations on limestone hills, rocks and walls, especially near the sea. It can be grown as a houseplant with bright direct light from a window or grow light. Use a coarse, well-drained soil, preferably a cactus mix. When grown outdoors, site for sun to part sun in well-drained soil. It seldom needs watering, but will grow in moist soils with good drainage. The plant tolerates maritime exposure, rocky and poor soils, and establishes itself quickly. The succulent leaves make it drought and dry soil tolerant. The plant is low to the ground, mat forming, and spreads aggressively and can be used for ground cover in a sunny position; although it can overwhelm other plants of similar height.

Diseases, Insect Pests, and Other Plant Problems:

No serious diseases or insect problems, except for occasional slugs and snails. Avoid wet or poorly drained conditions.
