Essential care

- Water: Moderate; water regularly during dry periods, allowing the soil to dry slightly between waterings.
- Soil: Light, well-draining soil. Avoid heavy clay and overly fertile mixes, which may reduce blooming.

Propagation
- Seeds: The preferred method — sow directly in soil or pots in early spring and keep moist until germination (7–15 days).
- Self-seeding: In mild climates, it can naturally reseed and bloom year after year.
Cat safety
- Classification: Non-toxic to cats, confirmed by ASPCA and horticultural references.
