Clematis for Zone 10

13 of the 220 Clematis 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.

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.

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.
