How to Grow and Care for Aeoniums or Tree Houseleek

Aeoniums, also known as Tree Houseleek or simply Aeonium, are a fascinating group of succulent plants that make wonderful additions to any garden or indoor space. With their showy, evergreen rosettes and low-maintenance requirements, these cactus-like beauties are a popular choice for gardeners of all experience levels. In this article, we’ll explore the ins and outs of Aeonium care, including key considerations like watering, light, soil, and more. We’ll also delve into the plant’s growth rate, size, and other characteristics, as well as how to incorporate Aeoniums into various garden styles and companion plantings.

Main Caring Considerations


Aeoniums are drought-tolerant plants that require minimal watering. In general, it’s best to let the soil dry out between waterings to prevent root rot. During the active growing season, water your Aeoniums once every 7-10 days, allowing excess moisture to drain away. In the winter months, reduce watering to once every 3-4 weeks, as the plants enter a period of dormancy.

Light Care

These succulents thrive in full sun to partial sun conditions. Ideally, Aeoniums should receive at least 6 hours of direct sunlight each day. However, they can also tolerate some shade, particularly in hotter climates where intense afternoon sun may cause leaf scorching. If you’re growing Aeoniums indoors, place them in a sunny windowsill that receives plenty of bright, indirect light.

Soil Care

Aeoniums require well-draining soil to prevent root rot and other moisture-related issues. They can grow in a variety of soil types, including acid, alkaline, neutral, loam, and sand. To ensure proper drainage, consider adding perlite, pumice, or coarse sand to your planting mix. If growing Aeoniums in containers, use a high-quality cactus or succulent potting mix for the best results.

Growing Region

Aeoniums are native to the Canary Islands and North Africa and are well-suited to USDA hardiness zones 4-9. They can be grown as perennials in warmer climates, or as annuals or container plants in colder regions where they can be brought indoors during the winter months.

Growth Rate, Height, Size and Spread

The growth rate of Aeoniums can vary depending on the species and environmental conditions. On average, these plants grow slowly to moderately, reaching their full size within several years. Aeoniums can range in height from just a few inches to several feet, with rosettes that can span anywhere from 2 inches to over a foot in diameter. Some species may also develop branching stems, giving the plant a tree-like appearance.

Season and Temperature


Aeoniums are generally hardy in USDA zones 4-9, but their specific hardiness can vary depending on the species. Most Aeoniums cannot tolerate freezing temperatures and should be protected from frost or brought indoors during the winter months in colder climates.


Pruning is generally not necessary for Aeoniums, as they maintain their shape quite well. However, you may wish to remove dead or damaged leaves to keep the plant looking tidy. If an Aeonium becomes too tall or leggy, you can trim the stem back to encourage a more compact growth habit.


Aeoniums typically produce showy, star-shaped flowers on tall stalks that rise above the rosettes. Flowering times can vary depending on the species, but most Aeoniums bloom in late winter or early spring. After flowering, the rosette will die, but new growth will emerge from the base or along the stem.


These succulents are generally pest-resistant, but they can occasionally be affected by common plant pests such as aphids, mealybugs, and spider mites. If you notice any signs of infestation, treat the plant with insecticidal soap or neem oil to control the pests.


Aeoniums are deer-resistant and can tolerate drought and salt conditions, making them a suitable choice for coastal gardens and other challenging environments.

Garden Styles

With their unique appearance and low-maintenance requirements, Aeoniums make excellent additions to a variety of garden styles, including city and courtyard gardens, coastal gardens, gravel and rock gardens, and Mediterranean gardens.

Companion Plants

When selecting companion plants for Aeoniums, consider other drought-tolerant, sun-loving plants with similar water and soil requirements. Some good options include other succulents like Echeverias, Sedums, and Agaves, as well as drought-tolerant perennials like Lavender, Yarrow, and Salvia.

Frequently Asked Questions

Are Aeoniums poisonous to pets?

Aeoniums are not considered toxic to pets, but it’s always a good idea to prevent your animals from chewing on your plants to avoid any potential health issues.

Can Aeoniums be propagated?

Yes, Aeoniums can be easily propagated by stem cuttings, leaf cuttings, or by dividing the offsets that form at the base of the plant.


Aeoniums are a captivating group of succulent plants that are both beautiful and easy to care for. With their striking rosettes, low water requirements, and adaptability to various growing conditions, Aeoniums make an excellent choice for gardeners of all experience levels.
