Daylily Planting Calendar and Bloom Season: Spring vs. Fall Planting Results

When to Plant

• Spring: After last frost. May not bloom first year.
• Fall: 30+ days before first frost. Best for strong first-year bloom.

Growing and Bloom Season

• Active growth: Mid-spring to first frost.
• Peak bloom: June–July (varies by cultivar/zone).
• Rebloomers: ‘Stella de Oro’, ‘Happy Returns’ — sporadic bloom into fall.

Fall Planting Advantage

Roots establish in cool, moist soil without top-growth demand. Crown is ready to explode in spring. This is why commercial growers prefer fall planting.
