When to Plant Lavender in Indiana

Growing Lavender in Indiana: Complete Guide

Lavender (Lavandula angustifolia) is a warm-season crop that needs a head start indoors before Indiana's last frost. Most Indiana gardeners begin seeds indoors around Monday, February 9, 2026 and move transplants outside around Monday, May 4, 2026, after the risk of frost has passed.

Because Indiana stretches across 4 USDA hardiness zones (5b, 6a, 6b, 7a), planting windows can shift by as much as two to four 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, Lavender needs the indoor head start that Indiana's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Lavender requires full sun (6+ hours) and low (drought tolerant once established) moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
