Those glossy, emerald-green rosettes perched atop branching stems look like something from another world. Tree Aeonium, also known as Tree Houseleek or Irish Rose, is a striking branching succulent shrub with smooth, upright stems reaching up to 2 metres tall, each crowned with a perfect, flattened rosette of fleshy, spoon-shaped leaves. Those leaves are a vibrant, glossy green, often taking on subtle coppery or purple tones in strong sunlight. In late winter through spring, mature rosettes send up tall panicles of small, star-shaped, bright yellow flowers, attracting pollinators.
Native to the Canary Islands and Morocco, this succulent thrives in the Western Cape’s Mediterranean climate. It needs full sun to partial shade—bright light maintains its compact form, though afternoon protection helps in hotter inland gardens. It demands very well-drained, sandy or gritty soil and, once established, is remarkably drought-tolerant. It handles coastal conditions and light frost well. Reaching 1–1.5m tall and wide, it’s perfect for rockeries, succulent gardens, large containers, or as a striking structural accent.
Key Features:
- Upright, branching stems topped with perfect rosettes of glossy, emerald-green leaves
- Tall clusters of bright yellow, star-shaped flowers in late winter and spring
- Water-wise once established; thrives in well-drained, poor soils
- Handles coastal conditions and light frost with ease
Gardening Note: Plant in full sun to partial shade in very well-drained, sandy or gritty soil. Water regularly until established, then allow the soil to dry completely between waterings. Reduce watering significantly in winter. After flowering, the rosette that produced the flower will die back—cut it off at the base. Easily propagated from stem cuttings taken in spring or summer. Hardy to light frost; in very severe inland valleys, a sheltered spot or container is recommended.
