🌿 About Bearded Iris
Growing Bearded Iris in Georgia: Complete Guide
Bearded Iris (Iris germanica) is fall-planted — it goes in the ground a few weeks before the first fall frost and overwinters for blooms the following spring. Depending on your zone, Georgia gardeners plant between August 20, 2026 (Zone 7a) and September 30, 2026 (Zone 9a).
Because Georgia stretches across 5 USDA hardiness zones (7a, 7b, 8a, 8b, 9a), 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 240 days to maturity, Bearded Iris fits comfortably within Georgia's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.
Bearded Iris requires full sun (6+ hours) and low; avoid wet soil moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
