Shelf Life: Best planted within 1 year for maximum germination
Planting Instructions:
Seed Preparation:
Cold Stratification: Physostegia Virginiana seeds benefit from cold stratification. Place seeds in a damp paper towel, put them in a plastic bag, and refrigerate for 4-6 weeks before planting. This helps break seed dormancy.
Sowing:
Timing: Sow seeds in late winter or early spring.
Method: Sow seeds on the surface of moist seed-starting mix. Lightly press the seeds into the soil but do not cover them, as they need light for germination.
Spacing: Sow seeds about 1-2 inches apart.
Germination:
Temperature: Maintain a temperature of 65-75°F (18-24°C).
Light: Provide bright, indirect light or place under grow lights.
Moisture: Keep the soil consistently moist but not waterlogged. Germination typically takes 2-3 weeks.
Transplanting:
Timing: Transplant seedlings to their permanent location after the last frost date when they are about 2-3 inches tall and have developed their first set of true leaves.
Spacing: Space plants 12-18 inches apart to allow for mature growth.
Care and Maintenance:
Watering: Water regularly to keep the soil moist, especially during dry spells.
Pruning: Deadhead spent flowers to promote prolonged blooming and prevent self-seeding.
