They are easy to grow, have few insect and disease problems and are available in many colors. In addition, they tolerate heat, drought, salt, compacted soil and various pH's. A daylily is available for almost any landscape condition. Culture Plant Characteristics Daylily leaves are long, narrow and arch from a central division back toward the ground. This central division is also called a fan.
Flowers rise above the foliage on a scape, and, as the name implies, last for only a day.
However, the 30 to 50 blooms per fan allow daylilies ot bloom over several weeks. Established daylily clumps often have several fans and can produce 200 to 400 flowers in a season. With this variation in height, daylilies can be used in both large and small landscape sites. Smaller cultivars can be used as edgers and foreground plants, while the larger daylily cultivars can be used in background plantings, as accents, or in front of tall hardscape elements such as fences and decks. Daylilies also work well in mixed borders and beds.
