Aeonium undulatum

About

Aeonium undulatum is a succulent, evergreen flowering plant in the family Crassulaceae. It is a subshrub, one of the larger species of Aeonium with an 8–12 inches (200–300 mm) rosette of bright, glossy green leaves often over a metre from the ground on a single, unbranched stem. Other rosettes do not branch off this stem (normally) but grow from the bottom, unlike most aeoniums. The plant is monocarpic so the flowering stem will die after producing its yellow inflorescence, which is normally after about 5 years.
