Beautiful, feathery plumes of creamy-white flowers on tall, elegant stems — perfect for shaded borders, woodland gardens, and moist areas.
Seed Treatment:
Cold stratification:
- Place seeds on a damp paper towel inside a sealed ziplock bag.
- Refrigerate at 34–40 °F (1–4 °C) for 6–8 weeks.
- If seedlings emerge during stratification, remove them carefully and plant immediately in pots.
Damp paper towel method is optional but effective for monitoring germination.
When to Sow:
Indoors: Start late winter to early spring after stratification.
Outdoors: Sow in autumn to allow natural cold stratification.
Optimum Temperature to Germinate:
59–68 °F (15–20 °C)
Germination Time:
8–12 weeks (56–84 days) after stratification.
Sowing Instructions:
- Sow on the surface of a moist, well-draining seed-starting mix.
- Do not cover seeds — they need light to germinate.
- Use grow lights to maintain 12–16 hours of light per day.
- Mist gently to maintain consistent moisture and HIGH humidity (use a dome)
Post Germination Care:
- Keep seedlings evenly moist — do not allow to dry out.
- When large enough to handle, transplant into individual pots.
- Harden off gradually before planting outdoors after last frost.
Growing Tips:
- Prefers partial shade to full shade.
- Grows best in moist, fertile, well-draining soil.
- Tolerates wet soils and is ideal for shady borders, streambanks, and woodland gardens.
- Mulch to conserve moisture.
- Minimal fertilization needed — compost or balanced fertilizer in spring is sufficient.
- Fully hardy perennial; dies back in winter and regrows each spring.
