Thimbleweed, Anemone virginiana
Ranunculaceae or Buttercup Family
 

Erect plant, to 3 feet, with 2-3 stem leaves.  Leaves with three leaflets, each irregularly lobed and toothed.  Flowers with 5 large white petals (actually sepals).  Fruit a cylindrical hairy, green, dry, berry-like structure.  Blooms in the summer.

Native that likes open woods.  In Wildwood, very common along the wooded edges of Wildwood Drive and the Riverway bike path.

Wood anemone is much shorter and blooms in the spring.  The flowers alone could easily be confused with those of roses or brambles, but those species are all woody shrubs.
