Aeonium arboreum ‘Atropurpureum’ is a fast growing, evergreen, sub shrub with an erect stalked habit. Its dark purple and bright green fleshy leaves are obovate with finely spined margins, up to 8cm long and 3cm across. Its leaves are held in a terminal rosette on the end of its stems. Its stems are initially green in colour becoming brown with age. Its bright yellow flowers appear in large panicles above the plant. These flowered stems die back once the seed matures.
Aeonium arboreum ‘Atropurpureum’, commonly known as ‘Purple Houseleek Tree’, is a nursery produced cultivar believed to have originated on the Canary Islands.
The etymological root of the binomial name Aeonium is derived from the ancient Greek aionos meaning ‘immortal’. Arboreum is from the Latin meaning ‘tree like’. Atropurpureum is derived from Latin meaning ‘very purple’.
