info		 Aeoniums are from the Mediterranean, making them a care-free plant for Bay Area gardeners. It is natural for aeonium heads to shed lower leaves during summer, becoming smaller and more compact. Once winter rains come the heads expand, adding many new leaves. This summer stress is a wonderful seasonal change in the Mediterranean garden.

Once established, most aeoniums will survive in Bay Area gardens without additional water. Water your aeoniums at least once a month during summer and they will look more full and lush. Be sure to let the soil dry between watering or you risk root rot or aphids.

Growing Notes

This aeonium is monocarpic, meaning that a head will die once it flowers. This particular species usually dies after blooming. This is part of what makes this plant so rare. Occasionally this can be overcome by removing the flower (but leaving the stem that held it) once the flower is past peak bloom. With some luck you’ll get new growth along that stem instead of having it die completely.
Aeonium tend to be brittle, so should be kept back from high traffic areas where physical damage is a possibility.
When over fertilized Aeonium grow lush and soft, attracting aphids.
