Sowing medicinal vervain
You can start your covered sowing early in March and April or directly in the ground starting from mid-May, after any risk of freezing has disappeared.
- When sowing in a sheltered place, ensure minimum temperatures of 60°F (15°C).
- Broadcast seeds and cover the seeds in a shallow layer of seedling soil mix.
- As soon as the first leaves appear, thin to 1¼ to 1½ inches (3 to 4 cm).
- When the plants have born 4 or 5 leaves, transplant them to a nursery pot.
- Transplant to the ground when the last frosts are past, towards mid-May.
If you’ve got a few seeds left over, sow them in bare spots of your vegetable patch, they’ll grow and attract pollinating insects there.
The only true enemies of common vervain are slugs, a bane in spring.
Caring for common vervain
Medicinal verbena, although it’s a perennial, is grown as an annual.
Common vervain is a plant that requires little care but some attention must be given in order to extend the blooming for a while.
- Remove flowers regularly (deadheading) in order to boost flower-bearing.
- Use the flowers in infusions either fresh or dried.
- In pots, containers or hanging arrangements, water when the soil has dried up.
- At the end of summer, adding fertilizer may rekindle the blooming and enhance autumn colors.
After the first fall frost spells, you can pull your medicinal verbena out; the following year’s blooming will be insignificant.
That is the time to common vervain flowers and leaves for your winter herbal tea.
