Nepeta in Zone 6

Will Nepeta survive a Zone 6 winter?

28 of the 28 Nepeta varieties in the Sow catalog are rated hardy through Zone 6, where winter lows reach -10°F to 0°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 Nepeta in Zone 6?

In Zone 6 the last spring frost typically lands around late April and the first fall frost around mid-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 Nepeta is best for Zone 6?

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.
