The turtlehead (Chelone obliqua) is native to the moist woodlands and mountains of Eastern and Midwest North America. It’s one of the few native woodland plants that blooms after spring — in this case from July through September.

Details

• Prefers partial shade but can take full sun if planted in wet soil.
• Prefers moist soil, even if it’s wet and clayey.
• Spreads to form large clumps.
• Hardy to Zones 3 to 9.

Care

• Pinching out the shoot tips in spring produces shorter, bushier plants.
