Aeonium nobile (Praeger) Praeger
Sempervivum nobile, Megalonium nobile
Aeonium nobile is a succulent plant that forms large rosettes up to 15 inches (37.5 cm) in diameter. The leaves are thick, fleshy, yellowish-green, occasionally reddish or brownish variegated especially along the margin, up to 2 inches (5 cm) long and up to 1.2 inches (3 cm) wide. After several years the plant matures and in late winter to spring produces a large inflorescence that rises on a red stalk to display a flattened capitate head over 1 foot (30 cm) wide and nearly as tall with many small, star-shaped, red flowers with white anthers.
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 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.
Feed during the growing season with a half strength balanced fertilizer, every month or so. Do not feed while dormant.
