Verbena aristigera

1. Cold Stratification:

  • Cold stratify for 2–4 weeks.

  • Place seeds in a moist paper towel, seal them in a plastic bag, and refrigerate.

2. Timing:

  • Start seeds indoors 6–8 weeks before the last frost.

  • Alternatively, sow directly outdoors after the last frost when the soil is warm.

3. Soil Preparation:

  • Use a light, well-draining soil mix.

  • Ensure the soil is moist but not waterlogged.

4. Sowing the Seeds:

  • Lightly press seeds into the soil—do not cover them, as they need light to germinate.

  • Space seeds 1–2 inches apart in trays or 6–12 inches apart in the garden.

5. Temperature & Light:

  • Keep at 65–75°F (18–24°C) for best germination.

  • Provide bright, indirect light or use grow lights for 12–16 hours daily.

6. Watering & Humidity:

  • Keep soil consistently moist but not soggy.

  • Use a mist sprayer to avoid disturbing the tiny seeds.

7. Germination:

  • Seeds typically germinate in 14–21 days.

  • Once seedlings appear, remove any humidity dome and ensure proper airflow.

8. Transplanting:

  • Once seedlings have 2–3 sets of true leaves, transplant them into pots or directly into the garden.

  • Space plants 12 inches apart in a sunny location.
