Echeveria shaviana (Mexican Hens) - An attractive and unusual succulent with short stemmed rosettes of blue-gray leaves that have very wavy crinkled margins that take on a pinkish tint if grown in bright light. In late summer appear the branched stems of pink flowers that are yellow in the interior. Plant in full sun to light shade (requires some shade in hot interior climates) in a well drained soil. Hardy to 23 F. This plant is native to the mountainous areas in northern Mexico (Tamaulipas, Nuevo Leon). This plant is the pollen parent for Don Worth's incredible hybrid Echeveria 'Afterglow' (E. cante x E. shaviana). 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 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 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. The description above is based on our research and observations of this plant growing in our nursery and in our own and other Santa Barbara gardens. We would appreciate hearing from anyone who has additional information or disagrees with what we have written. |
