Growing Guide

Sowing outdoors: Sow in early spring as temperatures begin to warm. Surface-sow — do not cover seeds; they need light to germinate. Keep seeds moist until germination.

Site and soil: Full sun to partial shade; well-drained soil, pH 6.0–6.5. Plants cannot withstand heavy frost, so avoid sowing when hard freezes are still expected.

Ongoing care: Keep well-watered through summer. Lightly trim plants after the first flush of blooms to tidy and encourage a second flowering. In warmer regions, established plants will self-sow reliably each season.
