Blue Vervain has a long history of use across Europe and into North Africa and western Asia. The ancient Druids of Ireland considered Vervain to have supernatural powers and held it in high esteem. Other cultures to have included Blue Vervain in their pharmacopeias included the Egyptians, Persians, Greeks, Romans and British. Later on, Dr. Edward Bach included Vervain in his 38 flower remedies to promote balance of body and mind. Blue Vervain has traditionally been used for a wide range of imbalances, including colds, coughs, flus and more.

Growing Guide
GROWING NOTES
Blue Vervain will grow to a height of 12-36” and begin to show dainty light purple flowers from mid summer into early fall. It will slowly spread and remain low to the ground, so allow plenty of space between plantings.

 

Vervain will grow best with full sun to partial shade. Soil should be well-drained.

MAINTAINING
Blue 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.
