Matthiola Incana Mix

🔍 About Matthiola Incana Mix

• Type: Cool-season annual or short-lived perennial (grown as an annual)

• Height: 12–30 inches (30–75 cm) depending on variety

• Bloom Time: Spring to early summer (can bloom into fall in cool climates)

• Fragrance: Many varieties are highly scented

• Light: Full sun to light shade

📅 1. When to Sow

• Indoors: Start seeds 8–10 weeks before last frost

• Outdoors: Direct sow after frost in cooler climates or late summer/fall in mild areas for early spring blooms

🌱 2. Starting Seeds Indoors

• Containers: Seed trays or small pots with drainage

• Soil: Fine, well-draining seed-starting mix

• Sowing Depth: Lightly press seeds into soil and cover with a thin layer (1/8 inch or 3 mm) of soil or vermiculite

• Water: Mist gently or bottom-water to avoid displacing seeds

🌡️ 3. Germination Conditions

• Temperature: 55–65°F (13–18°C) — cool temperatures improve germination

• Light: Not required for germination but place in bright light once sprouts appear

• Time: Germinates in 7–14 days

Tip: Avoid warm rooms. High temperatures can inhibit germination and reduce double-flowered plants.

🌿 4. After Germination

• Thin seedlings or transplant to individual pots when they have 2–3 true leaves

• Provide bright light (sunny windowsill or grow lights)

• Water moderately and ensure good air circulation

🌷 5. Transplanting Outdoors

• Timing: After hardening off and when temperatures stay above 40°F (4°C)

• Spacing: 6–12 inches apart depending on variety

• Soil: Well-drained, fertile soil (add compost if needed)

• Location: Full sun, especially in cool climates; partial shade in hot zones

📌 Tips for Success

• Cool weather = best blooms; heat reduces flowering

• Deadhead to prolong blooming, or let plants set seed to collect for next year

• Double vs. single blooms: You can't tell them apart at seedling stage; some gardeners sow extra and thin later

• Great for containers, borders, cutting gardens, and fragrant plantings
