When to Plant Daylily in Missouri

Growing Daylily in Missouri: Complete Guide

Daylily (Hemerocallis spp.) is planted as nursery stock — a container-grown or bare-root plant from a garden center, not seed. Depending on your zone, the ideal spring window in Missouri falls between March 20, 2027 (Zone 8a) and April 25, 2027 (Zone 5b); early fall works too, once summer heat breaks.

Because Missouri stretches across 6 USDA hardiness zones (5b, 6a, 6b, 7a, 7b, 8a), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 90 days to maturity, Daylily fits comfortably within Missouri's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Daylily requires full sun to part shade and low to moderate moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
