Linaria maroccana (Moroccan Toadflax)

Seed Treatment

Options:

  • Cold Stratification: Place seeds in a moist paper towel inside a sealed bag and refrigerate at 35–40°F (1–4°C) for 7–10 days.
  • OR Soaking: Soak in warm water for 6–8 hours before sowing.

When to Sow

  • Indoors: 6–8 weeks before your last frost date.
  • Outdoors: Direct sow in early spring after frost danger has passed or in late fall for natural stratification.

Soil Requirements

  • Prefers well-draining soil; tolerates poor, sandy soils.
  • Avoid overly rich soil, which can reduce flowering.
  • Ideal pH: 6.0–7.5

Light Requirements

  • Grows best in full sun (6+ hours daily).
  • Can tolerate light shade but may flower less vigorously.

Sowing Depth

  • Surface sow — seeds need light to germinate.
  • Press gently into the soil without covering.

Watering

  • Keep the soil consistently moist until germination.
  • Water at the base once seedlings are established.

Germination Time

  • Germinates in 10–20 days at 60–70°F (16–21°C).

Spacing

  • Thin or transplant to 6–9 inches (15–23 cm) apart.

Growing Tips

  • Linaria maroccana produces delicate, snapdragon-like flowers in vibrant shades—perfect for cottage gardens, wildflower meadows, containers, and borders.
  • Blooms from late spring through summer, especially if deadheaded regularly.
  • May self-seed gently in favorable conditions.
  • Best grown as a cool-season annual in most climates.
