Dr. Stout was born in Albion, Wisconsin on March 10, 1876. He worked between 1911 and 1948 at the New York Botanical Garden. In over 50,000 cross-pollination experiments, Dr. Stout produced over one hundred viable Hemerocallis hybrids, revolutionizing nursery breeding and popular interest in daylilies. Without a doubt, Dr. Stout's public renown rested largely on the knowledge and innovation he brought to the breeding of daylilies.
