Answer: Daylily hybridizers are striving to create more repeat blooming daylilies. In general, they will repeat best if given optimum growing conditions including high fertility, ample watering and lots of sunshine. Stella d'Oro is probably the most famous as well as one of the most frequent rebloomers but more are introduced every year. Many rebloom only once or possibly twice. There is a huge variety of colors, flower size and shape among the rebloomers. Burpee offers several in this year's catalog, daylily specialists such as Oakes http://www.oakesdaylilies.com/paradise/supplier/home.php?id=...
or Gilbert H. Wild
will offer a broader selection. Enjoy!
