Overwintering Princess Lilies (Alstroemeria) in Tennessee

Princess lilies (Alstroemeria cultivars) are hardy to Zone 7. Most of Tennessee is Zone 7, so they can stay in the ground with heavy mulch. Since they’ve already been dug up, store them in a cool (40–55°F), dark, frost-free place—not a heated basement—to keep them dormant. Replant after last frost.

Many online nurseries (e.g., Park Seed) carry princess lilies.
