Hylotelephium is a genus of flowering plants in the stonecrop family Crassulaceae. It includes about 33 species distributed in Asia, Europe, and North America.

Contents

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]

<span class="mw-page-title-main">Crassulaceae</span> Family of flowering plants

The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium-sized monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.

<i>Sedum</i> Genus of flowering plants

Sedum is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. The plants vary from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals. Various species formerly classified as Sedum are now in the segregate genera Hylotelephium and Rhodiola.

The flowers are held in dense heads and can be reddish or yellowish-white. A number of cultivars, often with purplish leaves, are grown in gardens as well as hybrids between this species and the related Hylotelephium spectabile (iceplant), especially the popular 'Herbstfreude'. Occasionally garden plants may escape and naturalise as has happened in parts of North America.
