When to Plant Crape Myrtle in Washington

Growing Crape Myrtle in Washington: Complete Guide

Crape Myrtle (Lagerstroemia indica) 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 Washington falls between February 17, 2027 (Zone 9b) and May 2, 2027 (Zone 5b); early fall works too, once summer heat breaks.

Because Washington stretches across 9 USDA hardiness zones (5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b), 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.

Crape Myrtle requires full sun (6+ hours) and low once established moisture. The Pacific Northwest's cool, wet springs delay soil warm-up; raised beds and black plastic mulch help jump-start the season.
