How to Care for Aeonium Arboreum (Houseleek Tree)

Aeonium arboreum, commonly known as Houseleek Tree or Tree Aeonium, is an evergreen succulent plant native to the Canary Islands. This stunning plant is known for its showy, rosette-shaped foliage, which adds a touch of exotic elegance to any garden or container. With a friendly and informative approach, this article will guide you through the primary care requirements for Aeonium arboreum, as well as provide helpful tips on how to achieve optimal growth and flowering for this lovely plant.

Main Caring Considerations


As a succulent, Aeonium arboreum prefers a low to average amount of water. During the growing season, it is essential to water the plant thoroughly and then allow the soil to dry out before watering again. In the winter months, reduce watering significantly, as the plant goes into a semi-dormant state. Overwatering can lead to root rot, so it’s crucial to strike the right balance.

Light Care

Tree Aeonium thrives in full sun to partial sun conditions. Providing your plant with at least six hours of direct sunlight per day will ensure healthy growth and vibrant foliage. However, if you live in an area with scorching summer temperatures, it is advisable to provide some afternoon shade to prevent sunburn or heat stress.

Soil Care

Well-drained soil is a must for Aeonium arboreum, as it helps prevent root rot while maintaining adequate moisture levels. This plant can tolerate a wide range of soil types, including acidic, alkaline, and neutral soils, as well as loam and sand. If you’re growing your Tree Aeonium in a container, use a high-quality, fast-draining succulent or cactus potting mix.

Growing Region

Aeonium arboreum is best suited for USDA plant hardiness zones 4 to 9, which cover a broad range of climates. This versatile plant can tolerate various environmental conditions, making it an excellent choice for gardens across many regions.

Growth Rate, Height, Size, and Spread

Tree Aeonium exhibits a moderate growth rate, reaching heights of 3 to 5 feet (90cm – 150cm) and a spread of 3 to 5 feet (90cm – 150cm) at maturity. The size of individual rosettes can vary between 48 inches to 60 inches (120cm – 150cm) in diameter, creating an impressive display when multiple rosettes are present.

Season and Temperature

Aeonium arboreum thrives in warm, sunny conditions and can tolerate temperatures in USDA hardiness zones 4 to 9. This plant is not frost-tolerant and should be protected from temperatures below freezing. If you live in a colder region, consider growing your Tree Aeonium in a container so you can move it indoors during the winter months.


Pruning is essential for maintaining a tidy appearance and promoting new growth in your Aeonium arboreum. Remove any dead or damaged leaves as needed, and trim back leggy stems to encourage branching. Pruning is best done during the growing season to allow the plant time to recover and produce new growth.


Aeonium arboreum produces showy, yellow flowers on tall, upright stalks during the spring and summer months. These flowers attract pollinators and add a burst of color to your garden or container.


Tree Aeonium is generally pest-resistant, but it can occasionally be affected by common succulent pests such as mealybugs, scale insects, and aphids. Regularly inspect your plant for signs of pests and treat with insecticidal soap or neem oil if needed.


This plant is deer-resistant and tolerates drought and salt well, making it an excellent choice for coastal gardens and arid landscapes.

Garden Styles

Aeonium arboreum is well-suited for various garden styles, including coastal gardens, gravel and rock gardens, Mediterranean gardens, beds and borders, and patio and container gardens. Its unique appearance and low-maintenance requirements make it a versatile and attractive addition to many landscapes.

Companion Plants

When selecting companion plants for your Tree Aeonium, consider other succulents and drought-tolerant plants that share similar growing requirements. Some good options include Echeveria, Sedum, Graptopetalum, Agave, and Senecio.
