Dahlia in Zone 8
Will Dahlia survive a Zone 8 winter?
124 of the 126 Dahlia varieties in the Sow catalog are rated hardy through Zone 8, where winter lows reach 10°F to 20°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 Dahlia in Zone 8?
In Zone 8 the last spring frost typically lands around late March and the first fall frost around mid-November. 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 Dahlia is best for Zone 8?
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.
