Aeonium Arboreum, native to northern Africa and the Canary Islands, thrives in coastal environments and can be grown as a perennial in warm climates or brought indoors during winter in colder regions. Known by various names like Pinwheel Desert Rose and Houseleek Tree, this succulent is a beautiful addition to any plant collection.
Size & Growth Typically, Aeonium Arboreum grows to about 3 feet tall and wide, though it can reach up to 4 feet in ideal conditions. Its shallow roots and attractive rosettes of leaves, which come in shades of green to maroon, make it look similar to Echeveria (Hen and Chicks). After flowering, the rosettes that bloom will die back.
Flowers & Fragrance In late winter or early spring, the plant produces small, star-shaped yellow flowers that grow in clusters on tall stems, adding a pop of color to your garden or home.
Light & Temperature Aeoniums need bright, indirect sunlight if kept indoors, so place them near a south- or west-facing window. Outdoors, they prefer full sun or partial shade. Protect them from cold weather, as they can tolerate brief drops to 25°F but will freeze if exposed to prolonged cold. In cold climates, it’s best to keep them outdoors in warmer months and bring them indoors during winter.
These plants are hardy in USDA zones 9B to 11B.
Watering & Feeding While Aeoniums are succulents, they need slightly more moisture than typical succulents. Water them using the “soak and dry” method—water thoroughly once a week, but ensure the soil dries out before watering again. During summer, they go dormant, so water less frequently, even just once a month. If grown outdoors, natural rainwater may suffice in the warmer months.
Avoid fertilizing during the summer dormancy. In spring and winter, when the plant is actively growing, use a balanced, water-soluble fertilizer at half strength once a month.
Soil & Transplanting Aeoniums thrive in well-draining soil, such as standard potting mix or sandy soil, and don’t need frequent repotting. Repot every two to three years using a shallow planter, preferably in autumn. Be gentle when transplanting, as their branches are fragile. If a branch breaks off, let it dry for a couple of days before planting it in fresh soil to grow a new plant.
Grooming & Maintenance Prune Aeoniums to maintain their shape and size, removing any dead or damaged leaves and stems.

Propagation To propagate, take stem cuttings from overgrown plants. Allow the cuttings to dry for a day or two before planting them in fresh soil. This helps prevent rot and encourages healthy growth.
Pests & Diseases Aeoniums are low-maintenance, but overwatering can lead to root rot and attract pests like spider mites and mealybugs. Ensure you don’t overwater to keep pests at bay.
Toxicity Aeonium Arboreum is non-toxic to people, pets, and children.
Invasiveness While not considered invasive, the cultivar Aeonium Arboreum Rosales has naturalized in a small area of Southern California. Be mindful when planting in areas where it may overwinter and reproduce.
Uses Aeonium Arboreum is perfect for beginners or those who aren’t great with plants, as it requires minimal care. It works well as a container plant or a specimen plant, and in warmer climates, it can be used as a groundcover in gardens.
