Aeonium haworthii Salm-Dyck ex Webb & Berthel.
Pinwheel, Pinwheel Aeonium, Haworth's Aeonium
Aeonium haworthii is a freely-branching succulent shrub that grows up to 2 feet (60 cm) tall with an equal spread. On branches are borne rosettes of bluish-green leaves that are keeled on the lower surface and often tinged red along the ciliate margins. The rosettes are up to 4 inches (10 cm) in diameter. Flowers ate very pale yellow to nearly white and sometimes tinged pink and appear in late spring. They rise above the foliage in a branched inflorescence.
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 hot or dry weather. Therefore, 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 Aeoniums 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.
