Rounded Global Status Rank: G4 - Apparently Secure
Reasons: This species is called Echeveria collomae by Kearney & Peebles (1951), and Dudleya saxosa subsp. collomiae by Bailey & Bailey, 1976, Hortus Third. No data is available from floras on abundance or habitat. This G-rank is based on AZHP's evaluation of D. saxosa ssp. collomiae as G4T4? It is my opinion that it should be re-evaluated as G3 because it is restricted to AZ.

Comments: Recognized as a distinct species by Kartesz (1994 and 1999), but sometimes treated as Dudleya saxosa ssp. collomiae.

Echeveria is a large genus of flowering plants in the Crassulaceae family, native to semi-desert areas of Central America, from Mexico to northwestern South America. The genus is named after the 18th century Mexican botanical artist Atanasio Echeverría y Godoy.

Description[edit]
Plants may be evergreen or deciduous. Flowers on short stalks (cymes) arise from compact rosettes of succulent fleshy, often brightly coloured leaves.[2] 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.
Cultivation[edit]
E. pulvinata flowers
Many Echeveria species are popular as ornamental garden plants. They are drought-resistant, although they do better with regular deep watering and fertilizing. Most will tolerate shade and some frost, although hybrids tend to be less tolerant. 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 re-rooted or propagated. In addition, if not removed, the shed leaves may decay, harboring fungus that can then infect the plant.
Propagation[edit]
They can be propagated easily by separating offsets, but also by leaf cuttings, and by seed if they are not hybrids.
