Aeonium arboreum is a striking, evergreen succulent known for its rosette-shaped leaves that form on woody stems. Originating from the Canary Islands, in its native setting, it typically grows 1 to 2 m. Characterised by its glossy, waxy green leaves, this houseleek tree produces small bright yellow, star-shaped flowers on tall, conical clusters from the centre of the rosettes. This drought-tolerant, frost tender plant thrives in well-drained soil and sunny locations, making it ideal for Mediterranean-style gardens or container planting. During the cooler months, this Aeonium is best grown under glass or in a conservatory to bask in the protected heat.
Plants will need protection in winter so move them to a dry, frost-free spot. In summer, water sparingly as they are well adapted to dry conditions and will draw on water stored in their succulent leaves. Grow on in a loam-based potting compost with added extra grit. Water moderately when in growth, not at all when dormant during the cooler months. Apply a balanced liquid fertiliser monthly throughout the growing season.
