Do Cabomba and Aeonium both belong to the same family?
Aeonium 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).
Galium aetnicum Galium aetnicum (common name Mount Aetna bedstraw) is a plant species in the Rubiaceae. The species is named for Mount Etna, the large and active volcano on the island of Sicily in the Mediterranean. The species is native to the island, and also to the Lazio and Abruzzo regions of mainland Italy. There are reports of the plant growing in Sardinia as well, but these are unconfirmed.
