Plant in a well-drained soil in full sun in cooler coastal gardens but will also take considerable shade. It is hardy to about 15-20 degrees F. It is great in the garden or in larger decorative pots.

The genus Echeveria is a member of the large Crassula family (Crassulaceae), which has about 1,400 species in 33 genera with worldwide distribution. Echeveria, with approximately 180 species, are native to mid to higher elevations in the Americas with the main distribution in Mexico and central America but with one species found from as far north as southern Texas and several species occurring as far south as Bolivia, Peru and possibly Argentina. The book "The genus Echeveria" by John Pilbeam (published by the British Cactus and Succulent Society, 2008) is an excellent source of information on the species and "Echeveria Cultivars" by Lorraine Schulz (AKA Rudolf Schulz) and Attila Kapitany (Schulz Publishing, 2005) has beautiful photos and great information on the cultivars and hybrids. It has been argued by some that the correct pronunciation for the genus is ek-e-ve'-ri-a, though ech-e-ver'-i-a seems in more prevalent use in the US.

Echeveria agavoides is an extremely variable species that has leaves that range from almost entirely green to those that are pink and with some that have deep red markings along the leaf margins. The species generally inhabits rocky canyons and arid hillsides of Central Mexico and found in the states of Aguascalientes, Durango, Guanajuato, Hidalgo, Jalisco, Querétaro, San Luis Potosí and Zacatecas, though there are reports of it being found as far north as Coahuila and as far south as Oaxaca. The genus Echeveria was named to honor Mexican botanical artist Atanasio Echeverría y Godoy in 1828 by the French botanist Augustin Pyramus de Candolle (DeCandolle) who was very impressed with Echeverría's drawings. Echeverría had accompanied the the Sessé and Mociño expedition (led by Martin de Sessé y Lacasta and Mariano Mociño Suárez de Figueroa) while exploring Mexico and northern Central America and had produced thousands of botanical illustrations. The specific epithet means "looking like an agave" in reference to this species narrow triangular leaves that are more acutely tipped than others in the genus. This resemblance also gives this species one of its alternate common names, Molded Wax Agave. It is also called Molded Wax, Molded Wax Plant, Wax Agave, Wax Echeveria and Carpet Echeveria.

Echeveria agavoides 'Romeo' is thought to be a mutation of E. agavoides 'Corderoyi' (AKA 'Ebony') that originated in the nursery of G. Köhres in Germany. It has also been called 'Red Ebony' and 'Taurus' but 'Romeo' is considered the valid name given by it originator - we have also noted a plant called 'Giant Purple' which may have been a selection from this plant. Our first plant of this cultivar came to us from Korean nurseryman SeongJu Hwang and additional stock was received from Joon Young Park. 'Romeo' differs from other Echeveria agavoides cultivars that we grow ('Lipstick', 'Maria', 'Prolifera' and 'Ebony') in that it is smaller than all but 'Lipstick' and has a leaf color that is more of a purple, gray color with less prominent red markings on leaves margins. 

This information about Echeveria agavoides 'Romeo' displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
