Phlox in Zone 5
Will Phlox survive a Zone 5 winter?
132 of the 132 Phlox varieties in the Sow catalog are rated hardy through Zone 5, where winter lows reach -20°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 Phlox in Zone 5?
In Zone 5 the last spring frost typically lands around early May and the first fall frost around early 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 Phlox is best for Zone 5?
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.
