Description

Aeonium smithii branches to form a small shrub up to 2 feet (60 cm) high. Its stems have whitish bristly hairs, giving them a shaggy appearance, though older stems tend to lose these hairs. During the winter-spring growing season, the rosettes of leaves are up to 6 inches (15 cm) across. The spoon-shaped or paddle-shaped leaves are velvety to the touch and glossy on the upper surface. They have wavy margins, with the waviness varying from slight to pronounced. The leaves also have lengthwise purple or brownish dashes, especially on the undersides, and these are thickened water-storing structures. The flower stalks are up 6 inches (15 cm) above the rosettes of leaves. They bear yellow flowers are 1 inch (2.5 cm) across.

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 (65–75˚F  / 18–24˚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 two. 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.. – See more at: How to Grow and Care for Aeonium.

Propagate Aeoniums by stem cuttings, except for unbranched species which die after flowering and are propagated from seed. Take cuttings when the plant is actively growing, usually fall in USDA zones 9 through 11. Aeoniums go dormant in summer; cuttings taken while plants are dormant don’t root. Each leaf rosette dies after it blooms…. – See more at: How to Propagate Aeonium.
