Sedum nussbaumerianum (Coppertone Stonecrop) Low growing subshrub to 8 inches tall by 2-3 feet wide with decumbent reddish-brown glabrous stems that hold elongating 3 inch wide rosettes of yellow-green to orange thick subterete (half cylindrical) 1 inch long leaves that are pointed at their tips. In late winter to spring appear the white lightly fragrant flowers in a flat topped umbel-like inflorescence. Plant in full sun to light shade in a well-drained soil. Irrigate little to occasionally. Hardy to at least 28° F. Color will be best in the sun with little water. A great plant for the rock or succulent garden or in a decorative container. Cut back stems and re-root when plants become too leggy. This plant was first discovered by Carl Albert Purpus at a sulfur spring in a ravine at Zacuapan in Vera Cruz, Mexico in 1906 or 1907 but was later described in 1923 by the German botanist Bitter who named it for Ernst Nussbaumer, the head gardener at the Bremen Botanic Garden in Germany. It was in cultivation under this name in California in 1944 or perhaps as early as 1933 as Sedum adolphii and was re-introduced by the Huntington Botanic Garden through the International Succulent Institute as ISI 1682 in 1986 from material collected in the wild by Charles Uhl at 550-600m on a rock outcrop near Cerro Gordo, Veracruz Mexico in 1978 (HBG 40419). This plant was given the marketing name Coppertone by Magic Growers Nursery of Altadena, CA in 2002. The late Dr. Henk t' Hart and Dr. Bert Bleij wrote the Sedum section in the lexicon "Illustrated Handbook of Succulent Plants: Crassulaceae" (Eggli, Urs (ed), Springer. Berlin, 2003) and noted this species to be very similar if not identical to Sedum adolphii however Robert Clausen in "Sedum of North America North of the Mexican Plateau" (Cornell University Press. Ithaca, 1975) listed them as often confused but separate taxa. The key in Clausen's book distinguishes Sedum nussbaumerianum by it having flowers all in the same plane, petals lanceolate 2.8-3.2 mm wide; principal leaves 5-8 mm thick, convex and obscurely carinate (keeled) dorsally while he noted that Sedum adolphii has petals at different levels in cymes, petals ovate-lanceolate, 3-3.5 mm wide; principal leaves 8-10 mm thick and strongly carinate dorsally. It has become naturallized in Sicily and on the Canary Island of Fuerteventura.
The information about Sedum nussbaumerianum displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant. |
