My early-blooming and repeat-blooming (which bloom both early and late in the summer) daylilies produce many flowers early in the summer, but the flowers are small and uniformly colored. My mid-season and late-season daylilies have large, multicolored flowers that are worth waiting for.
I planted these many years ago and I don’t remember what varieties they are. I bought the plants at a local garden center. Daylilies require very little care; you may want to remove the spent flower stalks before they produce seed, as some varieties (not these two or most other hybrids) will freely re-seed themselves. The old flower stalks are rather unattractive, so you will want to remove them at some point even if they don’t produce viable seed. Other than that, they seem to come back and produce masses of flowers every year with no care whatsoever.
