The botanical name for day lily is Hemerocallis, which means “beauty” and “day.” The individual flowers bloom for only one day, but the plants can provide continuous bloom from many buds. Re-blooming day lilies give flowers more than once during the summer season. Day lilies are among the easiest perennials to grow, and they thrive in many garden conditions. They can be fertilized in spring at the beginning of the growing season and watered no more than once every two weeks. They are heat tolerant and drought tolerant.
