Aeonium undulatum (Stalked Aeonium) - This upright growing succulent is an unbranched shrub that has somewhat metallic-green wavy 10-inch-long spoon-shaped leaves that form large rosettes on stout-stems to 2 to 4 feet tall that arise from a subterranean rootstock. Flowers are dark yellow in a terminal cluster rising up to 20 inches above the foliage, usually in summer, however this plant rarely flowers for us.
Plant in full sun (coastal) to light shade - can tolerate inland full sun but looks best with some shade there. Water occasionally to regularly in summer. Cold hardy to about 25-30° F. This curious looking plant always gets a second look - the smooth bare unbranched stems topped with a head of leaves gives one the impression of an odd-looking small palm tree.
Aeonium undulatum grows naturally in the middle elevations from 1,300 to 1,900 feet in the Laurel forest regions on the north of Gran Canaria, the largest island in the Canary Islands. The name Aeonium comes for Greek word 'aionion' or 'aionios' meaning immortal or everlasting for its succulent nature and presumed longevity. The specific epithet is in reference to this wavy undulating leaves. It received the Royal Horticultural Society's prestigious Award of Garden Merit in 1999, the same year that we started selling this wonderfully good-looking specimen plant.
