Sedum corynephyllum (Toliman Stonecrop) An interesting rare small sub-shrub that grows to 1 to 2 feet tall and wide with club shaped cylindrical light green leaves clustered at the branch tips with a compact inflorescence bearing only a few cupped barely open flowers with greenish yellow petals and long green sepals in late winter. Plant in full sun to light shade in a well drained soil with occasional irrigation. Hardiness is not known but the plant has not been bothered by temperatures hovering around 30 F. When young it resembles the common Sedum pachyphytum but eventually grows upward into a small sturdy shrub with a thickened trunk. Because of the interesting flowers, Joseph Nelson Rose originally described this plant in 1905 in the monotypic genus Corynephyllum and used the specific epithet viride to describe its green leaves but when combined into Sedum by Berger he needed to change the specific name as there was already a Sedum viride described from Japan so the name Sedum corynephyllum was chosen. The name comes from the Greek words 'koryne' meaning "club" or "pestle" and 'phyllon' meaning leaf for the shape of the leaves.
This plant grown from cuttings off a plant grown from seed that was collected at the Barranca de Toliman in Hidalgo, Mexico.
This information about Sedum corynephyllum displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate 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 that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
