Aeonium, a succulent plant native to northern Africa and surrounding areas, is grown for its attractive, waxy foliage that appears in the form of rosettes. Leaves grow in a variety of colors and patterns, from light green to variegated with deep purple. Aeonium plants reach up to 3 feet in height when provided with proper care. Because of their warm climate origins, Aeoniums cannot tolerate cold winter weather. Hardy in zones 9 through 11 only, the plants are grown in containers throughout the rest of the United States for easy transport indoors when temperatures drop in fall and winter.
Plant Aeonium in a medium-sized terracotta or clay pot with drainage holes in the bottom. Fill the container with a growing medium made of one part potting soil, two parts peat moss and one part coarse sand to provide adequate drainage and fertility.
Keep Aeonium plants outdoors in a location that receives full sunlight from May through September. Move indoors to a south-facing window just before the first frost of fall, and then move back outdoors in late April after the threat of frost is over.
Maintain a daily summer temperature of 68 to 86 degrees Fahrenheit and a nightly temperature of 50 to 60 degrees Fahrenheit. Keep at a temperature of 50 to 60 degrees Fahrenheit daily and 40 to 50 nightly during winter.
Water Aeonium when the soil has completely dried out, about once every seven to 10 days. Reduce watering frequency during winter to once per month, as the plant requires less moisture during this time. Never allow standing water to accumulate, or the crown may rot.
Feed the plant from May through September using an all-purpose houseplant fertilizer. Water both before and after applying to reduce the risk of root burn or injury. Apply at the rate recommended by the product's label for the best results.
Re-pot the plant during late fall once every two to three years using the same potting mixture in which Aeonium was initially planted. Increase the size of the container by 1 to 2 inches each time to allow room for further growth.
