Care Instructions:
This plant grows in neat clusters of ground-hugging rosettes, each with 8–10 fleshy, smooth leaves with tiny teeth near the tip and a chin-like underside. Bright yellow, daisy-like flowers rise on short stalks in summer. It tolerates sun and prefers minimal water during its active season. It’s an ideal choice for succulent collections, rockeries, or dry garden spots.
Light
Provide full sun for bright leaf color and abundant blooms. In hot climates, offer morning sun and light afternoon shade to prevent scorching.
Water
Water sparingly—roughly every 10–14 days during active growth, letting the soil dry out between waterings. Reduce water in winter to prevent rot.
Soil
Use a gritty, well-draining mix—such as cactus soil with extra sand or pumice. Avoid heavy or moisture-retaining soils.
Temperature
Thrives in warm weather and tolerates brief light frost when kept completely dry. Protect from sustained cold, moist winters.
Humidity
Low humidity preferred. Good airflow helps prevent mold around tight leaf clusters.
Fertilizer
No regular feeding needed. A light, half-strength cactus liquid feed in spring can support flowering.
Best Placement Ideas
- Sunny rock garden crevices
- Shallow containers or succulent trays
- Mixed alpine beds with similar succulents
- Bright green roof or gravel garden accents
Common Issues
- Root or crown rot from overwatering or winter damp
- Sunburn on leaves in extremely harsh sun
- Leaf drop from sudden temperature shifts
- Pests are rare—watch for mealybugs on rosette centers
Things to Watch Out For
- Don’t repot during blooming season—wait until dormancy
- Remove spent flower stalks to maintain neat appearance
- Clumps may outgrow pots every few years, requiring division
- Mark planting time to track watering and dormancy cycles
Propagation Tips
Divide clumps gently in spring or summer by removing offsets. These root quickly in well-draining mix. You can also propagate from seed sown in spring under bright, warm conditions.
Maintenance Tips
Keep soil clean and dry in winter. Skip watering until new growth appears in spring. Remove any drought-damaged leaves and tidy up old growth. Repot or refresh soil every 2–3 years to sustain vigor.
