Aeonium ‘Starburst’ is a visually striking succulent, known for its unique variegated rosettes. Its spoon-shaped leaves present a mix of green with irregular yellow banding, often developing vibrant pink edges when exposed to ample sunlight. Also known as Aeonium ‘Lemon-Lime’, this plant can grow rosettes up to 12 inches in diameter, making it a captivating addition to any collection. Understanding its specific care and propagation needs ensures this plant thrives, displaying its full spectrum of colors and distinctive form.
Caring for Aeonium Starburst
Light Requirements
Aeonium ‘Starburst’ thrives in bright, indirect light to maintain its distinct variegation and prevent leaf scorch. While it tolerates some direct sun, particularly morning sun, intense afternoon sun can burn the leaves, causing brown or white marks. If grown indoors, placing it in a south or west-facing window that receives several hours of bright, indirect light daily is ideal. Gradually acclimating the plant to increased light levels helps prevent sudden sun damage, especially when moving it from a shadier spot.
Watering Needs
The “soak and dry” method is recommended for watering Aeonium ‘Starburst’, ensuring the soil dries completely between waterings. This prevents root rot, a common succulent issue if the plant sits in overly wet soil. During its active growing season, winter to spring, the plant will require more consistent watering. However, during its summer dormancy, watering should be significantly reduced, providing moisture only when leaves begin to shrivel.
Soil and Potting
A well-draining soil mix is crucial for Aeonium ‘Starburst’, preventing water retention around the roots. A sandy loam or a regular potting mix amended with perlite or coarse sand is preferred over a cactus-specific mix, as aeoniums appreciate slightly more moisture. Using pots with drainage holes is also essential for proper water runoff. Repotting every two to three years with fresh potting soil supports continued healthy growth.
Temperature and Humidity
Aeonium ‘Starburst’ prefers cooler temperatures, with active growth occurring between 65°F to 75°F (18°C to 24°C). It is sensitive to frost and generally hardy in USDA zones 9b to 11b, tolerating temperatures down to around 25°F (-3.9°C). In colder climates, bringing the plant indoors or providing protection from freezing temperatures is necessary. Humidity is not a major concern, as the plant is adapted to drier conditions.
Feeding
Feeding Aeonium ‘Starburst’ occurs during its active growing season, from winter to spring. A half-strength balanced fertilizer applied monthly or every few months is sufficient. Avoid fertilizing during summer dormancy, as the plant will not actively absorb nutrients. Over-fertilizing can lead to problems.
Understanding Dormancy
A distinguishing characteristic of aeoniums, including ‘Starburst’, is their summer dormancy. During hot and dry periods in summer, the plant’s growth slows significantly or stops entirely. Rosettes may close tightly, and some outer leaves might dry or fall off, a normal protective mechanism to conserve energy and moisture. During this dormant phase, watering and feeding should be minimal, as the plant is not actively taking up water or nutrients through its roots.
Propagating Aeonium Starburst
Propagation of Aeonium ‘Starburst’ is achieved through stem cuttings. The best time for propagation is during the active growing season (spring or autumn), when the plant is most vigorous. To take a cutting, select a healthy stem with a rosette at the top, ideally 4 to 6 inches long. Make a clean cut just below a leaf node using sterilized scissors or pruners.
After taking the cutting, allow the cut end to dry and form a callus for a few days to two weeks in a cool, shaded area with good air circulation. Callusing prevents rot when the cutting is planted. Once callused, insert the stem about 1 to 2 inches deep into a pot filled with well-draining succulent or cactus mix. Water sparingly until roots develop (which takes a few weeks), and place the pot in bright, indirect light.
Troubleshooting Common Issues
Leggy growth
Leggy growth in Aeonium ‘Starburst’, characterized by stretched stems and widely spaced leaves, indicates insufficient light. Moving the plant to a brighter location with more indirect sunlight corrects this and encourages more compact growth. If the plant has become severely leggy, the top rosette can be cut and re-rooted as a new plant.
Rotting or mushy stems and leaves
Rotting or mushy stems and leaves are a sign of overwatering, particularly during the plant’s summer dormancy. Allowing the soil to dry completely between waterings and ensuring adequate drainage prevents this. If rot is present, the affected parts should be removed, and the plant should be allowed to dry out before repotting into fresh, dry soil.
Scorched leaves
Scorched leaves, appearing as brown or white spots, result from too much direct sun exposure, especially intense afternoon sun. Relocating the plant to a spot with bright, indirect light or providing afternoon shade prevents further damage. Introducing the plant to increased sunlight gradually helps it acclimate and reduces burning risk.
Pests
Aeonium ‘Starburst’ can encounter common succulent pests such as mealybugs, aphids, or spider mites. These pests often appear on the undersides of leaves or in leaf axils. Isolating affected plants and treating them with insecticidal soap or a cotton swab dipped in rubbing alcohol controls infestations. Regularly inspecting the plant helps detect and address pest issues early.
