Aeonium Arboreum is a succulent native to the Canary Islands. Zwartzkop, also known as Black Tree Aeonium, grows 18-36" tall with large glossy dark purple to black rosettes at the terminal end. This unique foliage brings depth and texture to rock gardens, containers, fairy gardens, or houseplant collections. This plant tolerates drought and goes dormant in the summer heat, with the primary growing season in winter. Aeonium Arboreum Zwartkop performs well in bright light indoors or partial shade with late afternoon sun outdoors. With little more than occasional water, Black Tree flourishes either as an outdoor annual, for its evergreen foliage outdoors in zone 10-11, or as a houseplant in bright light. This low-maintenance plant is monocarpic, with each 3-4" wide rosette producing yellow flowers at maturity and then dying off. For a more traditional succulent color, try Castello Paivae.
