Origin
This species is native to the Canary Islands. It grows on dry slopes and cliffs in northern Tenerife at elevations from 1,970 to 4,265 feet (600 to 1,300 m).
Description
Aeonium canariense is a succulent plant that forms large rosettes of velvety, bright green, occasionally reddish or yellowish leaves. The rosettes are cup-shaped with more or less erect inner leaves and grow up to 24 inches (60 cm) in diameter. Leaves are obovate to oblanceolate, apically rounded, ending abruptly in a short sharp point, up to 14 inches (35 cm) long and up to 4.8 inches (12 cm) wide. Flowers are star-shaped, 8- to 10-merous, greenish-yellow, and appear clustered in large conical racemes on up to 12 inches (30 cm) long peduncles. The racemes are up to 18 inches (45 cm) tall and 12 inches (30 cm) in diameter. The plant is monocarpic, which means the rosettes die right after flowering.
Hardiness
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 hot or dry weather. Therefore, they may go dormant in summer and do not require any water except in arid 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 Aeoniums need some moisture. If you are growing them in containers, repot them every 2 to 3 years with fresh potting soil.
Feed during the growing season with a half-strength balanced fertilizer every month or so. Do not feed while dormant.
