Iris in Zone 7
Will Iris survive a Zone 7 winter?
257 of the 258 Iris varieties in the Sow catalog are rated hardy through Zone 7, where winter lows reach 0°F to 10°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 7?
In Zone 7 the last spring frost typically lands around mid-April and the first fall frost around late October. 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 7?
Start at the top of the list above: it is ranked by how many gardeners actually save and grow each variety, which is a strong real-world reliability signal. Then narrow by your sun exposure and the mature size that fits the bed.
