Thimbleweed Seeds - Native Anemone Cylindrica with Unique Cylindrical Seed Heads

🌱 Site Selection

• 
  Light: Prefers full sun to part shade (at least 4–6 hours of sunlight daily).
  
• 
  Soil: Grows best in well-drained soils; tolerates sandy, loamy, or rocky soils.
  
• 
  Moisture: Adaptable, but prefers medium to dry conditions. Avoid overly wet sites.
  

🌾 Outdoor Direct Sowing

Fall Planting (Preferred)

• 
  Sow seeds outdoors in late fall so they experience natural cold stratification over winter.
  
• 
  Plant seeds on the soil surface and press them in lightly; do not bury deeply (they need some light for germination).
  
• 
  Water gently to settle seeds, then allow natural precipitation to take over.
  

Spring Planting

• 
  Requires cold stratification for 60–90 days before sowing. Place seeds in a moist medium (sand, peat, or vermiculite) inside a sealed plastic bag, refrigerate at 34–40°F for the stratification period.
  
• 
  After stratification, sow outdoors in prepared soil in early spring. Press into soil surface as above.
  

🌿 Indoor Sowing for Transplanting

1. 
   Start seeds indoors 8–10 weeks before last frost date.
   
2. 
   Cold stratify seeds (same as above) before planting in trays or pots.
   
3. 
   Use a well-draining seed mix. Press seeds into surface; do not cover heavily.
   
4. 
   Keep moist but not waterlogged; provide light (a sunny window or grow light).
   
5. 
   Transplant seedlings outdoors once they are 2–3 inches tall and after danger of frost has passed.
   

💧 Watering & Maintenance

• 
  Water seedlings regularly until established; afterward, plants are drought tolerant.
  
• 
  Minimal fertilization needed; thrives in lean soils.
  
• 
  Cut back old stems in late fall or early spring.
  
• 
  Naturalizes well—can spread by seed and rhizomes.
  

⚠️ Notes

• 
  Patience required: Germination can be slow and irregular (sometimes taking several weeks to months).
  
• 
  Best success comes with fall sowing directly in the garden.
  
• 
  Attracts pollinators like bees and provides interest with unique thimble-shaped seed heads.
