Orange Day Lily - Hemerocallis fulva

The Orange Day Lily is often so common that it is mistaken for a native species. However, it is actually an introduced escapee, and across much of the United States and parts of Canada it has become a weedy or invasive species. In Wisconsin it is classified as a non-regulated, terrestrial invasive species.

The flowers are orange and quite large, spanning individually from 3 to 4 inches across. The flowers are orange with red streaks and turn to yellow at the throat. They are held semi-erect or horizontally on the their stalks (rather than hanging downward). Each flower consists of 6 orange tepals (3 petals and 3 petal-like sepals that are similar in appearance).

Each flower lasts only one day.

Other names include: tawny daylily, ditch lily, railroad daylily, roadside daylily, outhouse lily, wash-house lily, corn lily and tiger daylily.
