Swamp Leatherflower (Clematis crispa) is a native perennial vine that is blooming in the wetlands of Pocosin Lakes National Wildlife Refuge. The sunlight along the Scuppernong Interpretive Boardwalk in Columbia creates the situation for optimum flowering and seed production. The bell-shaped flowers with curled edges vary in color from white to purple. The seed pod looks like an octopus that is green at first and matures to a brownish color. Bees work the flower diligently.
