The flowers are complemented by long, grass like foliage. The green foliage forms a mound and gracefully arches over. The flower stems originate from the center of the mound. The height of the plant, including the flower stem, ranges from 18 inches to four feet. The foliage persists throughout the growing season, which makes it desirable to use as a background for other perennials or annuals.
Daylilies prefer a well-drained soil in a sunny location.
They can grow in partial shade, but the number of blooms will be less compared to daylilies growing in full sun. Do not over fertilize daylilies. When too much nitrogen is applied, the plant grows at the expense of the flowers, and the foliage becomes weak and falls over. Diploid daylilies have the normal chromosome number in the cells of the plant. Chromosomes contain genetic information which determines the characteristics of the plant.
