Aeonium arboreum 'Zwartkop' ('Schwartzkopf') is also commonly called Black Rose Aeonium for its rosettes of intense purple, nearly black, leaves at the top of tall stems that resemble flowers. The head of these black rosettes are approximately 8 inches in diameter, smaller than ‘Cyclops’. Cone-shaped clusters of bright yellow star-shaped flowers rise above the foliage in spring. Full sun only in coastal or cooler climates. Provide partial shade in hot climates. Dormancy period can occur in hot summer months; reduce water during this time. Prune to remove the stem after it has flowered. Looks great in the California landscape planted in mass, in containers, or planted with other succulents of contrasting colors for maximum effect in the garden. Low maintenance. Low water requirements. High impact.
