Iris in Zone 10
Will Iris survive a Zone 10 winter?
53 of the 258 Iris varieties in the Sow catalog are rated hardy through Zone 10, where winter lows reach 30°F to 40°F. Hardiness is per-variety, not per-genus — the plants listed above are the ones that hold up; others in the genus are not rated for this zone.
When should I plant Iris in Zone 10?
In Zone 10 the last spring frost typically lands around rare and the first fall frost around rare. Planting after the last frost — or in early fall, so roots establish before the ground cools — gives the best establishment. Each plant page lists its own planting months.
Which Iris is best for Zone 10?
