Aeonium undulatum is one of the larger aeoniums with the rosette often over a metre from the ground on a single 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 when it flowers which is normally after about 5 years.
The specific epithet "undulatum" comes from the Latin unda, meaning "wave," and refers to the wavy leaves.. Other names include Sempervivum undulatum, Sempervivum youngianum, and "saucer plant"
