<p>'Got the Blues' will take away your blues! Four varieties of very dramatic light to dark shades of blue. Quite frost hardy. Includes 'Lilienstein' (blue, white on top), 'Elbaue' (light blue), 'Elbtalfruede' (mid-blue) and 'Bergzauber' (deep blue). Will overwinter in many areas, as cold as USDA zone 4.. Edible flowers also, add to winter salads for real drama!</p>
