Planting / harvesting notes

These seeds germinate well when stratified and sown in early spring and lightly covered with your growing medium after planting. Blue Vervain prefers full sun, but can grow in partial shade. In the wild, it prefers to grow in fertile, moist yet well-drained meadows, prairies, and riverbeds.

Seed keeping notes

Harvest the seeds after the flowers have faded and dried out. Check with your fingernail to see if the loosened seeds are firm and mature. Dry out the seeds.
