Daylily roots are generally long, slender and fibrous, whereas the lily is a true bulb. Foliage habit of the daylily is fountain like, with long slender leaves. The crown is the stem of the daylily. The flower scapes, except for a few bracts, are leafless flower stalks. These can be rooted to produce another plant.
Daylilies come in virtually every shape, size, bloom period, and foliage habit imaginable.
Bloom periods have been recorded across the globe in every month. However, in America the bloom season usually extends from late March through November. Growers in frost-free areas have recorded sporadic bloom throughout the entire winter. Undaunted, the hybridizers continue their quest to achieve the bluest blue. The latest introductions by the hybridizers include a fair number of daylilies that are deeply ruffled and banded with strongly contrasting colors.
