Rhododendron in Zone 9
Will Rhododendron survive a Zone 9 winter?
53 of the 114 Rhododendron varieties in the Sow catalog are rated hardy through Zone 9, where winter lows reach 20°F to 30°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 9?
In Zone 9 the last spring frost typically lands around late February and the first fall frost around early December. 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 9?
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.
