| ||Common Name: Aeonium-Black Rose |
Common Name (Alternative): Purple Crest Aeonium
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.
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.
‘Zwartkop’ is commonly grown in containers as a temperennial where it is not hardy. In such cases, the plants will grow as large as the container allows. Where plants are hardy enough to overwinter, they develop into shrub-like plants that can grow 5-6 feet tall.
‘Zwartkop’ tends to require more regular watering than ‘Kiwi’ and is more sun tolerant. It has a smaller, shallow root system and is less drought tolerant than some other Aeoniums. Though it requires good drainage, it can take somewhat heavier soil than ‘Kiwi’.

Aeonium is a tender perennial or "temperennial". It is hardy in zone 9 and warmer, but is commonly grown as an annual in colder zones and overwintered as a houseplant. Though Aeoniums are drought tolerant succulents, 'Zwartkop' prefers more regular watering than some others since it has a relatively small, shallow root system. It requires quite a bit of sun to draw out the dark purple coloring. A mildly acidic soil pH is best. Aeoniums are salt tolerant and deer resistant.
