White Turtlehead is a larval host for the Baltimore Checkerspot and other butterflies.  It attracts hummingbirds and lots of other pollinators.
 
     It's a non-aggressive, clump forming perennial with beautiful creamy white late-summer blooms with shiny, deep green leaves.  These blooms continue into fall providing a brilliant garden display and late-season nectar.
 
     Fun fact: The flower looks like a turtle's head (sort of...)
