Myosotis alpestris sylvatica (Forget-Me-Not)

Common Names: Alpine Forget-Me-Not, Woodland Forget-Me-Not
Life Cycle: Short-lived perennial or biennial
Hardiness Zones: USDA 3–8

For optimal germination rates, initiate seed propagation indoors under controlled conditions—unless the species exhibits a high sensitivity to root disturbance. This approach allows precise regulation of temperature, humidity, and light, improving germination consistency and seedling viability. Do not skip any recommended seed treatments, as they are essential for uniform and successful germination.

Seed Treatment

  • COLD STRATIFICATION: For improved germination, place seeds in a damp paper towel inside a sealed plastic bag and refrigerate for 2–4 weeks before sowing.
  • Check weekly: If seedlings sprout in the fridge, remove them gently and plant immediately.

When to Sow

  • Indoors: Start 6–8 weeks before the last expected frost.
  • Outdoors: Sow in late spring or early autumn for natural cold exposure.

Location & Soil

  • Light: Partial shade to full sun (in cooler climates)
  • Soil: Moist, well-drained; pH 6.0–7.5

Sowing Instructions

  • Depth: Surface sow—do not cover seeds, as they need light to germinate
  • Use grow lights to maintain 12–16 hours of light per day.
  • Moisture: Keep soil evenly moist
  • Humidity: Use a humidity dome or clear cover to maintain consistent moisture during germination. Open the dome BRIEFLY once per day to allow fresh air in and reduce mold risk. Remove the dome entirely once seedlings emerge.
  • Temperature: Use a heat mat to maintain a steady temperature of 18–21°C (65–70°F)
  • Spacing: Thin or transplant seedlings 10–15 cm (4–6 in) apart

Germination: 10 to 35 days AFTER stratification

Aftercare

  • Water regularly during dry periods
  • Fertilization: Apply a balanced liquid fertilizer every 4–6 weeks during active growth.
  • Mulching: A light layer of organic mulch helps retain moisture and suppress weeds.
  • Deadheading: Remove spent flowers to prolong blooming.
  • Winter Care: In cold regions, Myosotis alpestris sylvatica self-seeds and can return each year.
  • Excellent for borders, woodland gardens, and naturalized areas
