Aeonium is a rosette-forming succulent. Some Aeonium have leafy rosettes at the base; some have rosettes that sit atop sturdy stems. The leaves can be green, pink, deep red-black, and some have yellow edges or variegation. Aeonium can grow from a few inches tall to as tall as 4 feet.
Aeonium can bear brightly colored star-shaped flowers –yellow, red, white, or pink. Flowers may appear in spring, in winter, or in early summer.
Mid-summer is a rest period time for Aeonium. Water and fertilize Aeonium regularly during the growth time, but not during the growth pause in midsummer.
Aeonium is a genus of about 38 species. Aeonium is native to North Africa and the Canary Islands.

- Aeonium dies after blooming, so a new plant must be grown each year. Use leaf cuttings or seeds. Allow cuttings to dry for 24 hours, place the cutting in peat and sand mixture then set in a warm location.
- Aeonium rests from fall to early spring. Place Aeonium in a cool, bright location where it receives 5 hours of sunlight daily. Decrease water and withhold fertilizer.
