Growing Plumbago in Zone 7: Overwintering Strategies and Realistic Expectations

Plumbago Hardiness Limits

Plumbago is reliably hardy only to zone 8b. In zone 7, it will likely die back to the ground and may not return.

Plant in a sheltered, south-facing spot. Mulch heavily (6–8 inches of shredded leaves or pine straw) after the first frost kills the top growth.

Remove mulch gradually in early spring. Even with protection, regrowth is not guaranteed.

Consider hardy plumbago relatives like Ceratostigma plumbaginoides (hardy to zone 5) or blue-flowered salvias for reliable color.
