Daylily Seeds: Harvesting, Cold Stratification, and Growing On

Loretta found black seeds in daylily pods after flowering. Yes, they're viable—but like most hybrid perennials, seedlings won't mirror the parents. Still, it's a rewarding project.

Two Germination Methods

Outdoor (Easiest)

1. Prepare a weed-free seed bed in fall.
2. Sow seeds ¼ inch deep.
3. Let winter provide natural cold stratification.
4. Seedlings emerge after last frost in spring.

Indoor (Controlled)

1. Sow ¼ inch deep in moist potting mix in a pot.
2. Seal pot in a plastic bag.
3. Refrigerate (not freeze) 30–60 days to break dormancy.
4. Move to 75°F (24°C) under 40W fluorescent lights (8 inches above).
5. Germination in a few weeks.
6. Harden off 10 days before transplanting outdoors after frost.

Either way, you'll get a unique daylily mix—nature's surprise bouquet.
