SUCCULENT: Thick, succulent leaves in a basal rosette. The echeverias' appearance as miniature versions of the agave, have made them popular with collectors which has harmed their populations in many parts of the country. Collection or destruction in most areas is wisely prohibited.

FLOWERS: Bright yellow tubular flowers are supported on succulent, orange-red stems. Blooming mostly in mid-spring but also again in late summer or autumn, conditions permitting. Exceptional plants will have flowering stalks that exceed 50 cm tall

LEAVES: The elongate leaves are pointed, but are not sharp at the tips while the margins are smooth.

FRUIT: A group of usu. five dry capsules (follicles) that split open to reveal many seeds.


These plants and related taxa are very popular with botanists and as a result many names, including many rather fanciful names, have been applied to distinct populations, varieties and subspecies. Taxonomic revisions frequently result in a reshuffling of names.

Crassulaceae -- Stonecrop Family
