Echeveria is a large genus of flowering plants in the stonecrop family Crassulaceae, native to semi- desert areas of Central America, Mexico and northwestern South America.
Description
Plants may be evergreen or deciduous. Flowers on short stalks (cymes) arise from compact rosettes of succulent fleshy, often brightly coloured leaves. Species are polycarpic, meaning that they may flower and set seed many times over the course of their lifetimes. Often numerous offsets are produced, and are commonly known as "hen and chicks", which can also refer to other genera, such as Sempervivum, that are significantly different from Echeveria. Many species of Echeveria serve important environmental roles, such as those of host plants for butterflies. For example, the butterfly Callophrys xami uses several species of Echeveria, such as Echevelia gibbiflora, for suitable host plants. Even more, these plants are integral to the oviposition process of C. xami and some other butterfly species as well.
Taxonomy
The genus was erected by A. P. de Candolle in 1828, and is named after the 18th century Mexican botanical artist Atanasio Echeverría y Godoy. As of June 2018, the genus consists of about 150 species, including genera such as Oliveranthus and Urbinia that have formerly been split off from Echeveria.
