When to Plant Daylily in Alaska

Growing Daylily in Alaska: 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 Alaska falls between March 15, 2027 (Zone 8b) and June 15, 2027 (Zone 1a); early fall works too, once summer heat breaks.

Because Alaska stretches across 16 USDA hardiness zones (1a, 1b, 2a, 2b, 3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b), 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 Alaska'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. Alaska's long summer days accelerate growth, but frost can arrive early in August — season extension with row covers is essential.
