Biennial/Short-lived Perennial | Pollinator Friendly | Aromatic Foliage
Seed Treatment
• Soaking: Soak seeds in lukewarm water for 6–12 hours.
• Cold Stratification: Stratify seeds for 2 weeks at 40°F (4°C) using a moist paper towel in a sealed bag in the refrigerator.
If seedlings emerge during stratification, gently remove and plant immediately.
Germination Time: 7 to 35 days AFTER stratification
Optimum Temperature
Sow at 18–24°C (65–75°F)
Sowing Depth
Surface sow – press gently into the soil without covering. Light is required for germination.
Use grow lights to maintain 12–16 hours of light per day.
Light Requirements
Full sun preferred; tolerates partial shade
Post-Germination Care
Transplant when seedlings are strong enough to handle. Harden off before planting outdoors. Space 30–45 cm (12–18 in) apart. Pinch early to encourage bushiness.
Watering
Drought-tolerant once established. Water moderately and allow soil to dry between waterings.
Bloom Time
Produces showy flowers in the second year (biennial). Blooms in late spring to summer.
Soil Requirements
Prefers well-draining, dry to moderately fertile soil. Avoid heavy clay or soggy spots.
