Aeonium lancerottense (Praeger) Praeger
Sempervivum lancerottense (basionym)
Aeonium lancerottense is a an evergreen, perennial, densely branched shrub up to 2 feet (60 cm) tall. Numerous succulent, soft, green, smooth rosettes up to 6 inches (15 cm) in diameter, are densely held on thick branching stems and form a rounded shrub up to 3 feet (90 cm) wide. The cone-shaped flower heads are up to 1 feet (30 cm) across at the base and made up of many starry, pink flowers. They appear in summer and rise up on strong stalks up to 2 feet (60 cm) above the foliage.
USDA hardiness zones 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Aeoniums do not like really hot or dry weather. They may go dormant in summer and do not require any water, except in very dry conditions. In extreme heat, their leaves will curl, to prevent excessive water loss. Growing them in moist shade will keep them growing, but their true growth season is winter to spring, when temperatures are cool, 65 to 75 °F (18 to 24 °C), and damp. In the winter, water whenever the soil has dried out. Test by poking your finger down into the soil an inch or 2 (2.5 to 5 cm). Too much moisture or allowing them to sit in wet soil will cause root rot.
A sandy loam or regular potting mix is better than a mix specifically for cacti and succulents, since Aeonium need some moisture. If you are growing them in containers, repot every 2 to 3 years with fresh potting soil.
Aeonium lancerottense is endemic to the island of Lanzarote in the Canary Islands.
