This plant has shiny green foliage with white flower spikes that resemble a turtle’s head. Chelone glabra is often found in moist meadows, riparian forests and wetlands and likes full sun to partial shade.
The Baltimore checkerspot butterfly uses C. glabra as the primary plant to lay its eggs. Great for water gardens.
