Sedum album

Sedum is a genus of succulent, evergreen, herbaceous 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. The species name, album, from Latin means white in reference to the flowers.

White Stonecrop is easy to grow in dry to moist well drained soil in full sun, although it does tolerate light shade. The plant prefers sandy or gravelly soils of low fertility and the succulent leaves make it drought and heat tolerant when well established. The plant can be invasive and spreads along the ground by prostrate stems that root at the nodes, unless controlled. Because the plant is low to the ground, mat forming, and spreads aggressively, it can be used for ground cover in a sunny position; although it can overwhelm other plants of similar height. White Stonecrop is a recommended plant species for Triangle Area Green Roofs. White Stonecrop 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 White Stonecrop as mildly toxic if ingested, while others do not. 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 leaves, eaten in quantity, can cause stomach upsets.

Diseases, Insect Pests, and Other Plant Problems:
