Prolific Bloomer
One of the easiest perennials to grow, daylilies can give you years of reliable color. Each bloom lasts for one day, but a stem can easily produce two dozen or more buds, and the plant continues to send up new scapes throughout its bloom cycle. There's an embarassment of variety among cultivars, and besides color, height, petal texture and other things, they vary in period of bloom. So if you plan it right, you can have daylilies in bloom from early summer to fall.
