Daylily Bloom Times

I've heard that daylilies should bloom all summer long. However, mine seem to bloom one time for about 2-3 weeks and then they are done. Is there something I should be doing to prolong their blooming cycle?

Bloom time and length varies with the cultivar (cultivated variety). Many of the older daylily cultivars bloom once for 3 or 4 weeks in either early, mid or late summer. Some of the newer cultivars such as Stella de Oro and Happy Returns are repeat bloomers. These daylilies bloom for a few weeks, take a short rest, bloom and so on throughout the season. You may want to add some of the repeat bloomers or other daylily cultivars with a different bloom cycle to complement your current planting.
