Sedum morganianum (Burro's Tail) - A succulent plant with up to 2- to 3-foot-long trailing stems holding fleshy pale glaucus green slightly flattened leaves with terminal wine-red flowers held at branch tips spring into summer.
Plant in full sun or shade in a well-drained soil in a location it can trail over a wall or be used in a hanging basket and irrigate regularly, occasionally to infrequently. It has proven hardy down to down to at least 25° F. This versatile plant is an exceptional hanging basket plant with a more open habit and longer more pointed leaves than the similar Sedum burrito.
Sedum morganianum grows naturally on vertical cliffs at an altitude of 1,900 to 2,300 feet in the state of Veracruz, Mexico. It is a plant in the Pachysedum group of the genus, one of 22 subdivisions within the genus Sedum that the German botanist Alwin Berger created and that American botanist Robert Clausen expanded upon. This group includes more than 90 closely related tender succulent species from North America that appear to be more closely related to Echeveria, Pachyphytum and Graptopetalum than to plants in other sections in Sedum. Unlike these other Sedum that produce terminal inflorescences on the stem, plants in this group have lateral inflorescences.
Sedum morganianum was actually described 73 years before it was ever found in the in the wild and during that time it became very common in the American and European nursery trades and gardens worldwide having been cultivated since 1935 after the American botanist Eric Walther found it growing in hanging baskets at Jardín Flottante, a small nursery in the town of Coatepec, near Jalapa in the state of Veracruz, Mexico. It remained undescribed and it was even unclear what genus the plant belonged in until one of Walther's friends in California, Dr. Meredith Morgan, flowered his plant. With its small, terminal clusters of violet-pink flowers Walther was able to correctly associate it with the genus Sedum. When Walther described this plant in September-October 1938 Cactus and Succulent Society of America Journal (V.10 N.3 pgs. 35-37), he named the plant to honor Morgan. Since the plant was not found in the wild, he listed the type locality as unknown. Images accompanying this page from this article.
Many had since searched for where this plant grew in the wild and finally in 2008 it was found by the Mexican botanists David Jimeno-Sevilla and Amparo Alvalat-Botana who were working with Miguel Cházaro on a study of the flora around Tenampa, Veracruz. After a rancher named Carlos Ros told them of plants he knew about on his deer hunting property, Bellreguard Ranch (Rancho Bellreguard de Sochiapa) near the road from Orizaba to Veracruz, they located it growing on vertical cliffs in two different ravines called Mayatla and Ixcacotitla. The full story of this amazing discovery is in an article written by botanists Miguel Cházaro, David Jimeno-Sevilla and Amparo Alvalat-Botanav for the The Crassulaceae Database website titled The Sedum morganianum Habitat Discovered.
The information about Sedum morganianum that is displayed on this web page is based on research conducted in our nursery's horticultural library and from reliable online resources. We will also include observations made about this plant as it grows in our nursery gardens and other gardens that we have visited, as well how the crops have performed in containers in our nursery field. We also incorporate comments that we receive from others and welcome hearing from anyone with additional information, particularly if they share cultural information that aids others growing this plant.
