When to Plant Lavender in California

Growing Lavender in California: Complete Guide

Lavender (Lavandula angustifolia) is a warm-season crop that needs a head start indoors before California's last frost. Depending on your zone, California gardeners start seeds indoors between October 23, 2026 (Zone 11a) and February 14, 2027 (Zone 5b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because California stretches across 12 USDA hardiness zones (5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b, 10a, 10b, 11a), 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, Lavender needs the indoor head start that California'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. California's microclimates vary widely — coastal gardens stay cooler while inland valleys can reach extreme summer heat.
