Daylilies are best described as perennials. Perennials live for multiple years and come back each growing season from the same root system. Daylilies form their clumps and produce new flowering stems year after year, even though each individual flower lasts only a day. This distinguishes them from annuals, which complete their life cycle in one year; biennials, which typically flower in the second year; and ephemerals, which have very short lifespans.
