Growing Guide

Sowing: Surface-sow; do not cover seeds — light is required for germination. Keep seeds consistently moist at 55–75°F. Germination in 15–20 days.

Sowing rate: 1 oz per 1,000 sq ft | 2½ lbs per acre. Space plants 6 inches apart.

Site and soil: Full sun to partial shade; well-drained soil, pH 6.0–6.5. Tolerates a wide range of growing conditions. If plants become open or leggy, cut back and they will be bushy and blooming again within 4 weeks. Soil should be well-drained — soggy soil causes root rot.
