Aeonium undulatum (Stalked Aeonium) – Succulent plants

Aeonium undulatum is an evergreen, succulent subshrub and it is one of the larger species of Aeonium with somewhat metallic-green wavy up to 25 cm long spoon-shaped leaves that form large rosettes on stout-stems often over a 1 m from the ground. Other rosettes do not branch off this stem (normally) but grow from the bottom, unlike most Aeoniums. The blooms are a dark yellow in a terminal cluster rising up to 50 cm above the foliage, usually in summer. The plant is monocarpic so the flowering stem will die when it flowers which is normally after about five years.
