Northern Pitcher Plant (Sarracenia purpurea): Carnivorous! Height 8 to 24 inches. Leaves up to 12 inches. Each plat has a large leathery crimson flower with 5 petals dangling over the basal leaves. Leaves veined deeply red, inflated and in the shape of a pitcher. The flower attracts insects which fall into the "pitchers" which are partially full with water. Inverted hairs on the leaf surface prevent their escape. The plant extracts the nutrients from the water as the insect decomposes. Photo by Marc Shaffer.

Purple Loosestrife (Lithrum virgatum):  Alien. Similar to L. salicaria except the flowers are mostly in the leaf axils.

Thread-leaved Sundew (Drosera filiformis): Small puple flowers and long sticky leaves make tis bog plant easy to identify. Photo by Dimitri Tundra.

Spatulate-leaves Sundew (Drosera intermedia): Leaves are longer than the Round-leaved Sundew that follows. Mostly found on the coastal plains of the region. Photo by Dimitri Tundra.


Round-leaved Sundew (Drosera rotundifolia L.): This minute plant (less than 2 inches in height) is carnivourous. Insects get stuck to the apparent drops of dew and are digested in place. It does produce a simple white flower atop a central stalk. Location: All along the wet spots of Dobbin Grade, Dolly Sods North, MNF, WV.

Climbing Hempweed or Boneset (Mikania scandens): Round clusters of Boneset-like flowers. Grows in marshy area, covering other plants. Location: Merkle Wildlife Sanctuary, MD.
