Often appearing in holiday snaps from sunnier climes abroad, Aeonium 'Zwartkopt' is a branching, succulent evergreen perennial of open habit, with rosettes of deep blackish-purple leaves, and large panicles of small, starry, bright yellow flowers in early spring. Best grown under glass or in a conservatory to bask in the protected heat, or as a summer visitor to a sunny patio deck.


  • Garden care:
    Plant aeoniums in containers using a loam-based compost with added sharp grit to ensure free drainage. Position in full sun and water with rainwater, if possible, during the active growing season, allowing the compost to dry out slightly between waterings.

    Feed monthly with a balanced liquid fertiliser in spring and summer. During their winter dormancy, avoid watering altogether. These succulents are adapted to dry conditions, storing moisture in their fleshy leaves, so take care not to overwater.

    As they are not frost hardy, move them to a dry, frost-free space for winter to protect them from cold damage.
