Freshwater Plants

Freshwater plant species are rare within Shenandoah National Park. Most parkland is located near the crest of the Blue Ridge Mountains amid steep rocky terrain, providing few opportunities for wetland formation. The several wetlands that occur are small and found in the flatter areas such as Bearwallow, Big Meadows, and Pond Ridge.

Freshwater plants are highly adapted to living in water. They have few roots, less water conducting tissue, and have a weak structure because they grow in such a way that water provides them some mechanical support. The wetlands of Shenandoah tend to contain pools of standing water during the winter and spring, but become dry in the summer and fall.

Freshwater plants in Shenandoah are limited to species that can tolerate seasonal drying. Some common species include numerous grasses, sedges, and rushes, and more showy species such as cardinal flowers (Lobelia cardinalis), marsh willow herb (Epilobium palustre), and blue flag iris (Iris versicolor).

Although it’s native to these mountains, much of the beautiful mountain laurel you see blooming along Skyline Drive in June was planted by the Civilian Conservation Corps in the 1930s.
