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 10–28 days at 60–70°F (16–21°C).
Spacing
- Thin or transplant to 6–9 inches (15–23 cm) apart.

- Linaria maroccana produces delicate, snapdragon-like flowers in vibrant shades—perfect for cottage gardens, wildflower meadows, containers, and borders.

- May self-seed gently in favorable conditions.
