Long grown for its dramatic near-black foliage, this succulent adds drama and interest to containers and troughs, especially when combined with yellow or red plants. 'Zwartkop' is a wonderful backdrop plant that can show off many companion plants to maximum advantage
It forms large rosettes of fleshy, pointed spoon-shaped leaves that are completely near-black when grown in at least a half day of full sun. When grown in more shade, the rosettes are reddish purple with a green center. In climates where this plant is hardy, the foliage is evergreen. Bright yellow flowers are produced in large racemes from the center of the main rosette in summer.
