Aeonium Arboreum ‘Zwartkop’
Aeonium Arboreum ‘Zwartkop’ is a nursery produced cultivar from Aeonium Arboreum, so borns from gardening. Aeonium arboreum is native of continental Portugal and Madeira.
Aeonium Arboreum ‘Zwartkop’ was selected from Aeonium Arboreum to produce a plant with really dark red leaves, almost black. Leaves are grouped in rosettes which grow on tall stems, taller than the ones of the likely cultivar, Aeonium arboreum ‘Atropurpureum’. Actually, A. arboreum “atropurpureum”‘s red is less dark, and its rosettes are smaller than the ones of the cultivar ‘Zwartkop’. With the exception of these features, the cultivar ‘Zwartkop’ is really similar to the cultivar “Atropurpureum”. Flowers are also yellow, grouped in racemes: the blooming season is in summer. The plant is evergreen, perennial, and take the shape of a shrub, more towards a tree in A. arboreum than in other Aeoniums.
Put Aeonium Arboreum ‘Zwartkop’ under direct light to enhance its purple colour. Its growth season is spring: in summer the plant use to go dormant to bear the hot and dry climate. It curls the leaves in the case of excessive drought. In winter, water it only when the soil becomes completely dry. In summer, water it more or less twice a week. It needs a well-draining, sandy substrate. It doesn’t bear temperatures going below 0ºC.
Propagation can be realized form cuttings or seeds. Cuttings have to be taken in Spring or either autumn, when you have to cut the apical rosette and put it into the soil.
