The highest award a cultivar may receive from the American Hemerocallis Society. Only one Stout Silver Medal is awarded yearly. Also referred to as the Stout Medal. The Stout Silver Medal is given in memory of Dr. Arlow Burdette Stout, who is considered to be the father of modern daylily breeding in North America. This annual award – as voted by AHS Garden judges – can be given only to a cultivar that has first received the Award of Merit not less than three years previously.
