Aeonium Short Black

Aeonium 'Short Black' is a beautiful succulent subshrub that forms rosettes of deep purple to almost black leaves at the end of the branches. It branches profusely and can grow up to 12 inches (30 cm) tall, not as tall as Aeonium arboreum 'Zwartkop', but has a much better compact habit. Its leaves are usually greenish during the winter but develop dark colors during the summer.
