Hemerocallis fulva (Orange Daylily, Common Daylily, Tawny Daylily)

Native to Asia, Orange Daylilies are extremely hardy, quick to colonize, and produce gorgeous blooms in mid-summer. They divide every few years, producing entirely new plants that help outperform common unwanted garden plants (weeds). These are very common in suburban areas where applicable due to their deisreable qualities. However, these lilies compete with easter lilies, asiatic lilies, tiger lilies, and other daylilies (there are over 40,000 registered varieties of daylily available today).
