Aeonium plants are renowned in landscaping for their striking rosettes of lush green foliage.

Introduction

The Aeonium genus comprises around 35 species within the Crassulaceae family, alongside echeveria plants. Originating from the Canary Islands, Madeira, and Morocco, these succulents differ from typical drought-resistant varieties like agave and aloe due to their shallow roots. A notable characteristic of aeoniums is their generally monocarpic nature, meaning they die after flowering.

Exploring 8 Varieties of Aeonium Plants

Aeonium plants have thick leaves that grow in rosettes of varying shapes that range from compact, rose-like rosettes to wide-spreading rosettes with oblong leaves that stretch as wide as dinner plates. Some of the most popular types include:

  1. Noble aeonium (Aeonium nobile): The noble aeonium is easily identifiable by its large rosettes of fleshy, yellow-green to red-brown leaves. The leaves of this succulent grow up to two inches in length and one inch in width, and the entire rosette can reach up to 15 inches in diameter. The plant takes several years to mature, at which point it produces a large inflorescence that blooms small, red, star-shaped flowers.
  2. Green pinwheel (Aeonium decorum): Recognizable for its thick, dark-green rosettes that reach four inches in diameter, the green pinwheel can grow up to two feet tall. The leaves are often variegated along the edges and reach approximately two inches long. This plant flowers in late spring and summer, blooming small, star-shaped white or pink flowers.
  3. Aeonium leucoblepharum: This multibranched succulent is known for its rosettes of pointed leaves with thick stripes down the center of the leaves. Often variegated along the margins, these leaves can grow up to five inches long. Though occasionally red, the Aeonium leucoblepharum typically blooms yellow flowers with seven to ten petals.
  4. Tree houseleek (Aeonium arboreum): The tree houseleek is a popular aeonium with thick, waxy rosettes of leaves that form at the top stems that reach three feet tall in containers or six feet tall in a garden. In late winter to early spring, the tree houseleek forms racemes of yellow flowers and thrives in containers or rock gardens. After flowering, the rosettes die.
  5. Purple rose (Aeonium arboreum var. atropurpureum): Also called purple aeonium, the purple rose has stems that reach up to three feet tall and form rosettes of dark purple leaves when grown in bright light. This drought-tolerant plant blooms bright yellow flowers in spring
  6. Black rose (Aeonium arboreum ‘Zwartkop’): The black rose is recognizable for its clumps of brown stems that hold terminal rosettes that range in color from dark purple to black and reach up to eight inches in diameter. This plant flowers in summer, forming star-shaped, yellow flowers in conical clusters.
  7. Copper pinwheel (Aeonium ‘Sunburst’): Also known as the copper pinwheel, this branching aeonium has large, fleshy, variegated rosettes that grow up to 16 inches in diameter. The green leaves have yellow variegation with copper-colored tips that give the plant its name. The copper pinwheel is monocarpic, so after its star-shaped white flowers bloom, the plant dies.
  8. Kiwi aeonium (Aeonium haworthii ‘Dream Color’): The kiwi aeonium is a flashy plant that forms rosettes of vibrantly colored leaves. The plant grows up to three feet tall and wide, with variegated rosettes that can reach up to five inches in diameter. The leaves are easily recognizable for the rose-colored bands that form along their edges. Its yellow, star-shaped flowers bloom in summer.

How to Grow and Care for Aeoniums

When cultivating aeoniums, proper environmental conditions are key to their low-maintenance care.

  1. Sunlight: Outdoor aeoniums thrive in full sun to partial shade, especially in warm climates. Adjust for excessively hot summers or desert conditions by providing part shade.

  2. Container Selection: Opt for pots with adequate drainage to prevent root rot. Aeoniums thrive in containers due to their minimal soil requirements. Repot every two to three years using fresh potting soil.

  3. Soil: Unlike most succulents, aeoniums prefer regular potting mix amended with perlite for moisture retention.

  4. Fertilization: During the growing season, apply a half-strength balanced fertilizer monthly in winter. Avoid fertilizing during summer dormancy.

  5. Watering: Aeoniums need more water than typical succulents. In winter, water when the top two inches of soil are dry, but refrain from overwatering to prevent root rot. During summer dormancy, watering is unnecessary.

  6. Climate: A Mediterranean climate suits aeoniums best, with their growing season spanning winter to spring. They thrive in cooler, damper conditions, ideally around 65 to 75 degrees Fahrenheit. In summer, dormancy sets in, reducing watering needs. Leaf curling in summer is a natural mechanism to prevent excessive water loss.

By adhering to these guidelines, you can cultivate healthy and thriving aeoniums with minimal effort.

4 Steps for Propagating Aeoniums

Propagating aeoniums from cuttings is a straightforward process. Here are the steps to grow new aeonium plants:

  1. Cut: Use a sterilized knife to carefully cut a piece of stem with an attached leaf rosette.

  2. Dry: Place the cut end in a shaded area to dry out for several days. This step helps prevent rotting.

  3. Plant: Once the cut end has dried, plant it in regular potting soil mixed with perlite, ensuring the cutting stands upright. Choose a location with indirect, bright light for optimal growth.

  4. Water: Initially, lightly water the cutting until it establishes roots. Then, allow the top two inches of the potting soil to dry out between waterings to prevent overwatering and root rot.

By following these steps, you can successfully propagate aeoniums and grow new plants with ease.

Common Pests

Aeoniums are susceptible to common pests such as aphids, mealybugs, mites, scale insects, and even ants. Aphids and mealybugs produce sugary secretions that attract ants to the succulents, making it challenging to eliminate them, especially from plants with tight buds or rosette leaves. Placing ant bait near the affected plants can help draw out the ants. Once the ants are gone, you can focus on addressing the other pests by treating the plant with a spray of water or mild insecticidal soap.

Common Problems

Caring for aeoniums can be both straightforward and tricky, as some of their natural behaviors may cause concern for their well-being. Here are some tips for caring for aeoniums:

  1. Plant Leaves Falling Off: It’s normal for the bottom leaves of the rosette to shed, and the rosette may close up slightly. During the plant’s dormant stages in winter and summer, especially when grown outdoors, this behavior is typical and requires no intervention. However, if leaves are falling off unexpectedly, it could indicate stress. Providing the plant with water and observing if the rosettes open up and uncurl can help determine if it’s stressed.

  2. Browning Leaves: Excessive sunlight can cause sunburn, leading to white or brown edges on the leaves. Unfortunately, sunburn damage cannot be reversed. You can remove the affected leaves and relocate the plant to an area with less direct sunlight to prevent further damage.

  3. Dying Mother Branch: In branching aeoniums, the main mother plant may appear to be dying after flowering. To save the plant, use a sharp, clean cutting tool to remove the head where the rosette and flowers have bloomed. Although it may look unattractive initially, the branch should produce new shoots that will continue to grow and eventually flower.
