Medium tall plant, 2-3' tall. Leaves long,
pointed, toothed. Flowers large and showy, white, pink,
violet or deep purple, with four petals. Very pretty but
alien invasive weed. Common in disturbed areas along roads
and the Riverway, and near bridges. Blooms in late spring.
At first glance can be easily confused with
smooth phlox; however, smooth
phlox has five petals, and leaves that are not toothed and
are opposite each other on the stem.
