Turtlehead
Chelone glabra

Robust perennial herb that is 1-3' tall, and often grows as a single stem topped with a cluster of large, white flowers. Turtlehead is widely known as a landscape plant for mesic to wet gardens. It is also well suited for wetland restorations, rain gardens, and lake-edge restorations, especially in calcareous and peaty conditions. Many cultivars have been produced that may be mistakenly used in wetland restorations.
