Aeonium x hybridum
Aeonium x barbatum
Aeonium x hybridum, also known as Aeonium x barbatum, is a succulent plant that grows up to 6 inches (15 cm) tall and up to 12 inches (30) cm wide, forming a tufted bush. Leaves are arranged in terminal rosettes that grow up to 4 inches (10 cm) in diameter. They are green above with a brown median line, paler below, marked especially on the underside with many longitudinal oblong glands at first green and raised, later brown and collapsed. The compact flattish heads of golden yellow flowers appear in spring.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Aeoniums do not like hot or dry weather. 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.
