Growing Guide

Sowing: Direct sow outdoors in spring into a prepared, weed-free seedbed. Press seeds into the soil surface — do not cover. Light is required for germination. Keep moist until germination (14–28 days at 65°F). Sow 3–4 seeds per plant; thin to 18 inches apart.

Establishment: Drought tolerant once well-established. Not particular about soil — any well-drained soil with a pH of 6.2–7.2 will work. Full sun preferred.

Ongoing care: Deadhead spent blooms to encourage continuous flowering through first frost. Leave basal growth in place in fall for overwintering. Divide every 2–3 years to maintain vigor.
