Of the over 20,000 cultivars registered with the international registration authority, and over 40,000 registered with the American Hemerocallis Society (over 1000 new cultivars are registered yearly), the following representative selections are the ones most available from U.S. nurseries and include many of the more popular and proven cultivars. Bloom refers to relative bloom time with early=late June, mid=July, late=August in zones 4-6; decrease by 1-2 weeks for each zone warmer, add 1-2 weeks for each zone colder. Flower size of small=1-2" across, large=over 4" across.
