Aeonium aureum, also known as Greenovia aurea, is an attractive, succulent that usually has a solitary rosette up to 10 inches (25 cm) in diameter. The simple, pale apple-green leaves flush out in winter and close up in tight, rounded balls in the summer months. Mature plants send up a stiff, erect inflorescence of bright yellow flowers. It is very similar to Aeonium dodrantale, but it has larger rosette and usually doesn't form offsets unless it is a hybrid with A. dodrantale.
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °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.
