Aeonium (tree houseleek) is a genus of about 35 species of succulent, subtropical plants of the family Crassulaceae.
 Many species are popular in horticulture.
 The genus name comes from the ancient Greek "aionos" (ageless).
 While most of them are native to the Canary Islands, some are found in Madeira, Morocco, and in East Africa (for example in the Semien Mountains of Ethiopia).
Haberlea is a monotypic genus of flowering plants in the family Gesneriaceae.
 The only member of this genus, Haberlea rhodopensis, is endemic to several mountains in Bulgaria, especially the Rhodope mountains, and small part of northern Greece.
 Common names include Orpheus flower and resurrection plant because of the remarkable ability of "Haberlea" to survive very long periods of desiccation.
