Will Rhododendron survive a Zone 10 winter?

15 of the 111 Rhododendron 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.

When should I plant Rhododendron in Zone 10?

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.

Which Rhododendron is best for Zone 10?
