Sunlight
Full sun to partial shade; thrives in open grassland conditions, tolerates light shade in warm climates
Watering
Water regularly during seedling establishment; drought-tolerant once mature, avoid overwatering to prevent root rot
Temperature
Tolerates cool spring temperatures, sensitive to extreme heat above 30°C; short-term frost-hardy to -2°C
Characteristics
- Leaf: Pinnately compound, small oval leaflets arranged in pairs along fine, delicate stems
- Flower: Tiny pea-like blooms, pale pink to white, clustered at terminal stem nodes

Care Guide
Watering
Keep soil consistently moist during active growth phases
Fertilization
No regular fertilization needed; fixes atmospheric nitrogen via root nodules. Avoid high-nitrogen fertilizers, as they can inhibit nitrogen fixation
Eggshell powder topdressing：Crush dried eggshells into fine powder, sprinkle lightly around plant bases; avoid direct contact with stems to prevent fungal growthPruning
- Trim back spent flower heads to encourage extended blooming if grown ornamentally
- Mow or cut to ground level after senescence to incorporate biomass into soil as green manure
- Thin dense patches to improve airflow and reduce risk of fungal disease
