Plants were used in China before development of the written Chinese language. References to daylilies appeared in European herbals in the 15th century. By the 1890's, daylilies had been introduced to American gardens. The great virtue of the daylily is its ease of cultivation.
Plants are tough, reliable, and with few disease and pest problems.
They will grow almost anywhere but do best in full sun or partial shade in well drained soils supplied with organic matter. Clumps of strap-like leaves give rise to branching flower stalks in summer, each flower lasting a single day. New flower buds develop continuously to extend the flowering season. Flower colors, sizes, and forms are enough to suit every taste. About 38,000 cultivars of daylilies are registered with the American Hemerocallis Society.
