Echeveria (named for Atanasio Echeverria, an excellent Mexican botanical draughtsman). Crassulaceae. Stemless or somewhat caulescent succulents. Leaves fleshy, but usually broad and flat, commonly making dense, rosettes: fls. borne in loose spikes or racemes or sometimes paniculate, but never in a flat cyme; calyx deeply 5- parted; sepals usually elongated and narrow, unequal, commonly spreading but sometimes erect; corolla 5-angled, usually strongly so, very broad at base; stigma- lobes united below, very thick and nerveless, erect but often spreading at tip; stamens 10, 5 attached near the middle of the petals, the other 5 either free or attached lower down on the corolla: carpels 5, erect; ovules and seeds many.—More than 60 species of this genus have been described. Most of them have been in cult, in Washington and at the New York Botanical Garden, although but few are in the trade. It is confined almost entirely to Mex., one species extending into the mountains of W. Texas, and one or two species extending into Cent. Amer. Many of the species are valuable for flat bedding on account of their compact rosettes and highly colored foliage. For cultural notes, see Cotyledon (with which it has been united by many authors).

Echeveria is a large genus of succulents in the Crassulaceae family, native from Mexico to northwestern South America. The genus is named after the 18th century Mexican botanical artist, Atanasio Echeverría y Godoy. Many of the species produce numerous offsets, 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 Echeveria species are popular as garden plants. They are drought resistant, although they do better with regular deep watering and fertilizing. Most will tolerate shade and some frost, although hybrid species tend to be less tolerant. They can be propagated easily by separating offsets, but may also be propagated by leaf cuttings, and by seed if they are not hybrids. Echeverias are polycarpic, meaning that they may flower and set seed many times over the course of their lifetimes.

Most lose their lower leaves in winter; as a result, after a few years, the plants lose their attractive, compact appearance and need to be rerooted or propagated. In addition, if not removed, these shed leaves may decay, harboring fungus which can then infect the plant.
