Aeonium Arboreum - Houseleek

Position Aeonium arboreum in a bright location with plenty of natural light, ideally receiving some direct morning or late-afternoon sunshine. Plant in a free-draining cactus and succulent compost, preferably with added horticultural grit or perlite to prevent waterlogging. Water thoroughly when the upper compost has dried, allowing excess water to drain away, and reduce watering during periods of slow growth or dormancy. Unlike many succulents, Aeoniums often grow most actively during the cooler months and may become semi-dormant in hot summer conditions. Feed sparingly with a diluted cactus fertiliser during active growth. Keep frost-free, ideally above 5°C, and avoid placing the plant near cold draughts or radiators. Remove any dried lower leaves as necessary and repot when the plant becomes crowded.

Aeonium arboreum belongs to the Crassulaceae family and originates from the Canary Islands, where Aeoniums are a distinctive feature of the local flora. The name Aeonium comes from the Greek word aionios, meaning 'everlasting', a reference to the long-lasting nature of its succulent foliage. Unlike many familiar succulents, Aeoniums are adapted to cooler-season growth, often slowing down during the hottest part of summer. Mature rosettes can produce impressive, cone-shaped clusters of small yellow flowers, although the flowering rosette usually dies afterwards, while other branches can continue growing.
