Chelone Glabra ‘White Turtlehead’

Chelone glabra (White Turtlehead)

Chelone glabra, commonly known as White Turtlehead, is an upright herbaceous perennial renowned for its elegant white flowers that resemble the head of a turtle. This native plant blooms from late summer to early fall, producing clusters of snapdragon-like flowers that attract pollinators, including bees and butterflies. Its glossy, lance-shaped green leaves provide a lush backdrop to the blooms, creating a visually appealing addition to rain gardens, moist meadows, or alongside water features.

Found naturally in wetlands, stream banks, and low-lying areas across eastern North America, White Turtlehead thrives in USDA hardiness zones 3–8. This perennial prefers consistently moist to wet soils, making it an excellent choice for rain gardens, bog gardens, or planting near ponds. It grows to a mature height of 2–4 feet with a spread of 1–2 feet, offering structure and vertical interest in shaded or partially shaded areas.

Chelone glabra is also the primary host plant for the endangered Baltimore Checkerspot butterfly, making it an ecologically valuable choice for native and wildlife-friendly gardens. Its ability to thrive in wet, challenging conditions while requiring minimal maintenance makes it a standout performer for naturalized landscapes.
