Species in the genus, formerly included in Sedum, are popular garden plants, known as sedum, stonecrop, live-for-ever, or orpine. Horticulturalists have hybridized many of the species to create new cultivars. Many of the newer ones are patented, so may not be propagated without a license.

Taxonomy

Hylotelephium telephium and related species have been considered in a number of different ways since first being described by Linnaeus in 1753, including as a section of Sedum by Gray in 1821,[1] or a subgenus. But these taxa are quite distinct from Sedum morphologically.[2]

Hylotelephium is one of a group of genera that form a separate lineage from Sedum, and is closely related to Orostachys, Meterostachys, and Sinocrassula.[3][4]

The separation of the genus has not been universally adopted, for instance a Missouri Botanical Garden website states "Upright Sedums were at one point separated into the genus Hylotelephium, but are now generally included back in the genus Sedum."[5] One of Kew Garden's online databases also lists Hylotelephium as a synonym for Sedum.[6]

Etymology

Hylotelephium means 'woodland distant lover'. 'Hylo' is derived from Greek, meaning 'forest' or 'woodland'. 'Telephium', also derived from Greek, means 'distant-lover'; the plant was thought to be able to indicate when one's affections were returned.[8]
