Hemerocallis

Common name: Daylily

Hemerocallis is a genus of hardy herbaceous perennials native to Asia, widely cultivated around the world. Each daylily flower lasts only a single day, but each plant produces many buds over a long blooming season. Daylilies are famously adaptable and low-maintenance, earning a reputation as one of the easiest garden perennials.

Fun facts

  • There are over 90,000 registered daylily cultivars.
