Aeonium arboreum (Atropurpureum)

Sun Exposure

As with most succulents, Aeonium plants grow best in full sun to partial shade. In hot summers and desert conditions, light shade may be necessary.

Mature Plant Size

Size will vary greatly with variety. Some Aeonium varieties are low growing and get only a few inches tall, with rosettes an inch or two across. Others will branch out and grow 3-4 feet tall with plate-sized rosettes.

Bloom Period

Most Aeonium bloom in late winter or spring.

Using Aeonium in Your Garden Design

When grown in the garden, Aeoniums command the most attention in masses. Tall varieties can look like bonsai when they get shrubby. You can trim them if they get leggy. The cuttings will readily root and make new plants,  helping you fill out your planting area.

Needing so little soil, Aeoniums make great container plants. You can get a closer look at their unique features in containers, and have better control over their growing conditions. In high humidity or rainy areas, you may not need to water them, although they do need regular water. Keep close tabs on them and use your judgment. Using regular potting soil, rather than a fast draining soil for succulents, will help maintain their moisture level.
