Do Bulb Plants Produce Seeds?

Yes, But They're Usually Propagated by Division

Bulbous plants (tulips, daffodils, lilies, daylilies) flower and can set seed if not deadheaded. However, seed-grown plants take 3–5 years to reach flowering size.

Why Division Is Preferred

• Offsets (bulblets) are clones—identical flowers next year.
• Faster: divide in fall, replant, bloom next spring.
• Maintains cultivar traits.

Seed Uses

Breeders use seeds to create new hybrids. Gardeners may collect species seeds (e.g., species tulips) for naturalizing.

So your daylilies do produce seeds, but dividing the clump is the practical way to increase them.
