Plant Needs
Sunlight
Full sun to partial shade; tolerates intense direct sun in cool temperate climates, with partial shade recommended in extreme summer heat
Watering
Allow soil to dry completely between waterings; highly drought-tolerant, avoid overwatering to prevent root rot
Temperature
Extremely cold-hardy to -20°C; withstands high summer heat when provided with well-drained soil
Characteristics
- Leaf: Tiny, fleshy needle-like green leaves arranged in dense whorls along trailing stems
- Flower: Star-shaped bright yellow blooms in flat-topped terminal clusters
- Stem: Slender trailing stems that root at nodes to form continuous dense mats
Care Guide
Watering
Water when the top 2–3 cm of soil is fully dry; reduce watering during prolonged rainy periods
Fertilization
Diluted balanced feed once every 2 months. Use a diluted, low-nitrogen fertilizer to avoid excessive foliage growth that reduces drought tolerance
Eggshell powder topdress：Crush clean, fully dried eggshells into fine powder; sprinkle lightly on soil surface around plants; avoid direct contact with stems to prevent rotPruning
- Trim back overgrown mats in early spring to maintain a compact, tidy form
- Remove dead flower heads after blooming to prevent self-seeding in unwanted areas
- Thin dense patches to improve airflow and reduce risk of fungal growth in humid conditions
