Dr. Arlow Burdette Stout (1876-1957) was an American botanist and the pioneer breeder of the modern hybrid daylily.
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.
