Horse's Tail Sedum morganianum

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.  

Sedum morganianum, or Burro's Tail, is a succulent plant producing trailing stems up to 24 inches long with triangular-shaped fleshy blue-green leaves. It is an attractive plant in a hanging container that allows the trailing stems to be highlighted. The leaves are quite delicate, do not tolerate heavy foot traffic, and will break off if manipulated. Cuttings and dropped leaves root easily, making propagation a simple process. The plant has terminal pink or red flower clusters that appear in the summer.

Burro's Tail prefers high light interior environments such as a windowsill with at least partial sun, dry soil, fresh air, and shallow pots. Tepid water should be used to water plants and reduce watering in the winter. Allow the soil to dry out between watering and fertilize lightly once or twice during the growing season. The plant is native to Mexico and the Dominican Republic, but when grown outdoors in cooler climates, the plant will tolerate temperatures down to 40 degrees F. When grown outdoors, site for sun to part sun in well-drained soil. The plant tolerates rocky and poor soils, and establishes itself quickly. The succulent leaves make it drought and dry soil tolerant.

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. Pest/disease problems can occur due to overwatering.
