Wildflowers of the Rocky Mountains and the Texas Hill Country are colorful, thriving in brilliant sunshine.  Spring flowers of the Appalachians, however, seem more dainty and subtle.  They peek out from dense foliage on cool overcast days, adding to the mystique of these mountains.
   Take, for example, Squirrel Corn (Dicentra canadensis), an odd member of an obscure family of plants, Fumariaceae.  Its better known members are bleeding hearts and a close relative, Dutchman's Breeches.
