Germination
7-14 daysTiny seedlings with cotyledons emerge from soil; very delicate appearance
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to prevent crowding. Protect from strong wind.
Seedling to Young Plant
3-4 weeksTrue leaves develop; plants form a small rosette with several leaf pairs
Continue moderate watering. Begin hardening off transplants if growing indoors. Fertilize lightly with balanced fertilizer every 2-3 weeks.
Vegetative Growth
3-6 weeksSpreading stems develop, creating a mounding habit; leaves are serrated and gray-green
Reduce watering frequency as plant matures. Apply light mulch to conserve moisture and suppress weeds. Pinch back tips early to encourage bushiness.
Flowering
10-16 weeks (late spring through fall)Dense clusters of small flowers (called umbels) appear at stem tips; continuous blooming through season
Deadhead spent flowers regularly to promote continuous blooming. Water during extended dry spells. No fertilizer needed; excess nitrogen reduces flowering.
Seed Production & Dormancy
Variable; winter dormancy 3-5 months in cold zonesFlowers fade and seed pods develop; in late fall, foliage may turn reddish; plant enters winter dormancy in cold climates
Allow some flowers to remain for self-seeding if desired. Cut back dead stems in spring after new growth appears. Mulch in zones 3-4 for winter protection.

Harvest Tips
Canadian verbena is grown for ornamental flowers rather than harvest. Deadhead faded flower clusters to encourage continuous blooming throughout the season.

Fun Facts
- 🌱 Canadian verbena is native to the central and southern United States, despite its common name; it's sometimes called drumhead verbena or mock vervain.
- 🌱 Verbena flowers have a fascinating structure: what appears to be a single flower is actually a dense cluster (umbel) of dozens of tiny individual florets that open sequentially over days, extending the bloom time.
- 🌱 The name 'verbena' comes from Latin and was historically associated with medicinal and spiritual significance in ancient European herbalism, though Canadian verbena was unknown to the ancient herbalists.
