Aeonium simsii is native to the Canary Islands. It occurs on Gran Canaria in rocky sites at elevations that range from 1,640 to 6,230 feet (500 to 1,900 m).
Description
Aeonium simsii is a well-branched succulent that forms dense clumps of short, stout branches that end in cup-shaped rosettes of yellowish-green leaves with longitudinal, brownish stripes on the lower surface and conical cilia along the margins. It can grow up to 12 inches (30 cm) tall, while the rosettes can reach a diameter of 4.8 inches (12 cm). The leaves are thick, fleshy, lance-shaped, measuring up to 2.4 inches (6 cm) long and 0.8 inches (2 cm) wide. They may sometimes have a purplish-brown line down the middle of the upper surface.
The flowers are yellow, star-shaped, and 7- to 9-merous. They appear in spring in flat-topped (or nearly so) clusters on densely leafy stalks that can grow up to 12 inches (30 cm) tall.
