Aeonium arboreum

Aeonium arboreum, the tree aeonium, tree houseleek, or Irish rose, is a succulent, subtropical subshrub in the flowering plant family Crassulaceae.

Description

Aeonium arboreum grows as a less branched subshrub and reaches stature heights of up to 2 metres. The more or less upright or ascending, smooth, not net-like patterned stem axes have a diameter of 1 to 3 centimetres.

Their leaves are in flattened rosettes with diameters of 10 to 25 centimetres at the end of the stem axes together. Young leaves are pressed tightly together. The obovate to oblate lanceolate leaf blade is pointed toward its apex and wedge-shaped at the base. It is 130 to 380 mm (5 to 15 in) long, 25 to 115 mm (1 to 4+1⁄2 in) wide and 1.5 to 3 millimetres thick. The green, usually purple-colored, glossy leaf surface is almost bare. The leaf margin is set with curved eyelashes.
