Hemerocallis are in the lily family, though some consider them to be more closely related to amaryllis. They differ from lilies as they do not grow from true bulbs.

Hemerocallis / daylilies are easy to grow, colorful, extremely accommodating and will perform under almost all conditions. The daylily can be characterized as a clump-forming, herbaceous perennial with fibrous or somewhat tuberous roots. Preferring well drained, well mulched and sunny positions, it will tolerate extreme damp to very dry sandy soil. Flowers will be more prolific in better soil and in full sun. In heavy shade, foliage may be more abundant with few flowers. Daylilies prefer at least six hours a day for the paler shades, less for the darker reds and purples. If flowers fade, wilt or burn in direct sun, move them to filtered shade.

Daylilies can range in height from 8 inches to 5 feet, and flower size can be as small as 2 inches or as large as 8 inches. Daylilies may bloom the year that they are planted, even from a relatively small plant. They will reach mature size in about three to four years. Daylilies are long-lived if given even moderate care and can be planted just about anywhere.

Daylilies are grown for their rainbow of colors, and many shapes and sizes. There are daylilies in bloom from late spring until autumn. A well-established clump produces many buds and daily blooms for a month or more and many varieties have more than one flowering period. When choosing daylilies, light-colored flowers show up better at a distance than darker ones. Dark-colored varieties standout when planted against a light backdrop.

Besides serving as specimen plants, daylilies are used for color in shrub borders and in perennial beds. They are excellent ground covers on slopes and a recommended material for erosion control.
Use daylilies for blending structures with the terrain, to fill voids or to supply contrast and seasonal color. They have a naturalizing effect to blend fences, decks, steps, statues, driveways or shrubbery with the surrounding landscape. If planting smaller cultivars in containers, choose varieties that repeat their blooming cycle during the growing season.
