Tree Houseleek Aeonium arboreum
ABOUT
Aeonium arboreum, commonly known as the tree houseleek, has a distinct appearance characterized by its succulent attributes. This plant features rosettes of fleshy, waxy leaves that often grow in a spiral pattern and can vary in color from deep green to burgundy, sometimes with a glossy or matte finish. Each rosette appears almost like a large, singular flower composed of spoon-shaped leaves. The plant has a branching habit, with stems that bear the rosettes at their ends, resembling a tree-like structure. During certain seasons, the tree houseleek may produce pyramidal clusters of small, star-shaped flowers. These blooms can range in color, typically yellow, adding a vibrant contrast to the foliage. The overall aesthetic is one of sculptural, geometric forms, making it a popular choice in succulent gardens and as an ornamental plant in various landscapes.

WaterThe Tree Aeonium, or Aeonium arboreum, should be watered sparingly and allowed to dry out between waterings as it is susceptible to root rot if kept too moist. During the growing season, which is generally from fall to spring, water the plant approximately once a week with about 8-10 ounces of water, adjusting for climate and indoor conditions. In the summer, when the plant is dormant, water even less frequently, providing just enough to prevent the leaves from shriveling, about once every two to three weeks. It’s important to avoid watering directly into the rosette as this can cause rot, instead water the soil directly. Ensure the pot has good drainage to avoid standing water.
LightTree Aeonium thrives in bright, indirect sunlight and should be placed in a spot where it can receive at least six hours of sunlight daily, but protected from harsh midday sun which can scorch the leaves. An east or west-facing window is ideal for providing the right light conditions inside a home. If grown outdoors, semi-shaded areas that mimic their natural habitat work best, especially in hot climates.
TemperatureTree Aeonium prefers mild temperatures and does best in a range from 40 to 100 degrees Fahrenheit. They can survive brief periods of colder weather down to around 30 degrees Fahrenheit, but prolonged exposure can be harmful. The ideal temperatures for promoting growth are between 65 and 75 degrees Fahrenheit. This succulent is not frost-tolerant and should be protected or moved indoors during cold winters.
PruningTree Aeonium benefits from occasional pruning to encourage a fuller shape and to remove any leggy or overgrown stems. The best time to prune is in the growing season, typically fall to spring. You can prune as often as needed to maintain shape but avoid over-pruning as it may stress the plant. Cuttings taken during pruning can often be used for propagation.
CleaningAs needed
SoilThe best soil mix for Tree Aeonium should be well-draining and sandy. A mixture of cactus potting soil with perlite or pumice can create the ideal growing environment. Slightly acidic to neutral pH, ranging from 6.0 to 7.0, is optimal for the health of the Tree Aeonium.
RepottingTree Aeoniums should be repotted every two to three years, or when they outgrow their current container. The best time to repot is during their dormant period, which is typically after the flowering season.
Humidity & MistingTree Aeonium prefers a dry climate and does well in low humidity conditions. They are well-suited to arid environments, so it is best to avoid high humidity to minimize the risk of rot.
Suitable locationsIndoor

Life cycleThe life cycle of the Aeonium arboreum, commonly known as the tree aeonium or houseleek tree, begins as a seed, which requires well-drained soil and adequate sunlight to germinate. Upon sprouting, the seedling grows into a succulent with a rosette of leaves, which further develops into a mature plant with a branching, woody stem. As it matures, the tree aeonium produces clusters of yellow, star-shaped flowers at the ends of the branches, typically blooming in late winter to spring. After pollination, which is often aided by insects, the flowers develop into seed capsules containing numerous tiny seeds. Post flowering, particularly after a significant bloom, mature rosettes may die, but the plant continues to grow by forming new rosettes on other branches. The tree aeonium is a monocarpic species, meaning that individual rosettes will die after flowering, but since the plant is branching, not all rosettes will necessarily flower at once, allowing the plant to live for several years.
PropogationPropogation time
Spring to early summer
The Aeonium arboreum, commonly known as the Tree Aeonium or Tree Houseleek, is mostly propagated through stem cuttings. This method is popular due to its simplicity and effectiveness. The best time to propagate is during its active growth period, which is typically in spring or early summer. To propagate by stem cuttings, you should select a healthy, mature stem and cut a segment approximately 2 to 4 inches (5-10 cm) long using a clean, sharp knife or scissors. The cut end should be allowed to callous over for a few days to prevent rot when planted. Once calloused, the stem can be placed in well-draining soil and kept in a warm spot with indirect sunlight, ensuring that the soil remains moist but not waterlogged. Roots will typically develop within a few weeks, after which the new plant can gradually be acclimated to more direct sunlight.
