Growing Daylilies from Seed: Cold Treatment and Light Needs

Seed Harvest

Collect seeds from brown, splitting pods after bloom. Seeds are shiny black half-moons.

Stratification and Germination

  • After Christmas, plant ½ inch deep in moist potting soil.
  • Seal pot in plastic bag; refrigerate 60 days (not freezer).
  • Move to 70°F; sprouts in weeks (sporadic).
  • Place under 40-watt shop light 8 inches above.

Transplanting

Prick out at several leaves. Harden off 10 days after frost. Plant in garden. Blooms in year 2. Hybrid seeds won't match parent.
