Verbena Germination Information

Verbena is the botanical name for Vervain
Verbena Seed Germination How to Sow Verbena:
  • Sow indoors, 12-14 weeks before last frost, at a temperature of 70-75°
  • Expect germination in 20-25 days
  • As darkness is necessary for germination, sow seeds at a depth of 4 times the size of the seeds or cover the seed flat with black plastic
  • Remove the cover at first sign of germination. Seedlings are subject to damping off
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Verbena:
Transplanting: Transplant when there are at least two sets of true leaves

Spacing: Space 12 inches apart in full sun

Soil: Site in a light, rich, well-drained soil. Allow the soil to dry out between waterings

Temperature: Site in full sun, provide 55° nights

Additional Care:  As a group they are very tolerant of drought, exposure, wind, heat, humidity, and pollution. The perennial types can get straggly, so cut back hard in early spring or resow seeds each year
