Herbaceous perennial native to eastern US that blooms in spring and is pollinated by hummingbirds, butterflies and bees.  The genus name is derived from the Latin work for eagle as the pink & yellow flower petals resemble an eagle's claw.  It tolerates a variety of soils and is deer resistant.  It freely self-seeds, blooming the second year.  It is a host plant for the duskywing butterfly.  
 
Direct sow just below soil surface in fall.  Can also be started indoors or planted in early spring but will require cold moist stratification.
