Sedum Dendroideum Sedum Dendroideum Habit and Cultural Information Category: Succulent Family: Crassulaceae (Stonecrops) Origin: Mexico (North America) Evergreen: Yes Flower Color: Yellow Bloomtime: Winter/Spring Height: 1-3 feet Width: 3-4 feet Exposure: Sun or Shade Seaside: Yes Irrigation (H2O Info): Low Water Needs Winter Hardiness: 20-25 F Sedum dendroideum (Tree Sedum) - Although the epithet and common name imply this plant to be a tree it actually is a small shrub, though we do grow a larger form called dendroideumThis particular form grows to 1 to 3 feet tall spreading to 3 to 4 feet wide and rooting along stems to form a large low mass. The 1 1/2 inch long green leaves of this plant are spathulate with an almost ovate leaf that have subepidermal glands along the leaf margin that turn reddish in full sun. These glands distinguish it from the very similar Sedum praealtum that is often listed as a subspecies of Sedum dendroideum (S. dendroideum ssp. praealtum). Both plants have clusters of small vivid yellow star-like flowers that form above the foliage in late winter and early spring. A great drought tolerant small shrub with nice foliage color and cheery yellow spring flowers. Useful in street medians and other locations where a low growing, low maintenance, drought resistant plant is needed.. This plant came from the Huntington Botanic Garden as accession number HBG 21756 and was received by them from Reid Moran (RM 14795) in May 1968 from material collected in Mexico at La Cañada in the state of Queretaro. Information displayed on this page about Sedum dendroideum is based on the research conducted about it in our library and from reliable online resources. We also note those observations we have made of this plant as it grows in the nursery's garden and in other gardens, as well how crops have performed in our nursery field. We will incorporate comments we receive from others, and welcome to hear from anyone who may have additional information, particularly if they share any cultural information that would aid others in growing it.
