This Aeonium “Zwartkop” is commonly known as the Black Tree Aeonium or Black Rose Plant. Zwartkop, as all you linguists will know, means black head in German. It hales from the Canary Islands and although not truly “black” is, at its peak, not far off being as good as it gets . These spectacular subtropical succulents are frost tender and therefore need to be overwintered in the greenhouse to be brought out again for their summer holidays. It is naturally a winter grower and at this time the florets become greener, it is during its semi-dormant time throughout the summer months when it is at its darkest. These particular specimens have never flowered but when they do they will be a dramatic cascade of yellow. They are planted close to the entrance in our Bright, Light and Night bed and are one of the plants most commented on. A bit like Marmite, you either love them or you hate them. I love both.
