Planting and careBlue Vervain is best sown direct in late summer or early fall. If starting in spring, stratify seeds in refrigerator for 1-2 weeks. Small seeds are light dependant germinators with naturally low germination rates. Moisten starting medium and lightly tamp into soil, and keep moist until seeds start to germinate, typically 3-4 weeks. Transplant outside once the last freeze has passed and plants show first (or second) set of true leaves.
