About

Hemerocallis fulva, the orange day-lily, tawny daylily, corn lily, tiger daylily, fulvous daylily, ditch lily or Fourth of July lily (also railroad daylily, roadside daylily, outhouse lily, track lily, and wash-house lily), is a species of daylily native to Asia. It is very widely grown as an ornamental plant in temperate climates for its showy flowers and ease of cultivation. It is not a true lily in the genus Lilium, but gets its common name from the superficial similarity of its flowers to Lilium and from the fact that each flower lasts only one day.

How to grow it

Hemerocallis fulva has been cultivated in Europe, and naturalized in many countries there, since at least the 16th century. Several modern cultivars exist which are grown as ornamental plants. As most of the varieties in cultivation are sterile triploids, and all spread via subterranean bulb offsets, the most common (and simplest) method of propagation is by root- or bulb-division.

H. fulva are long-lived perennials, and are adaptable to a range of climatic conditions. The species is a vigorous grower in nearly any location, thriving even in difficult areas where other plants do not thrive. The plants grow well in full sun to open shade, and are drought tolerant. H. fulva is winter hardy to UDSA Zone 4.

Where it grows

Orange daylily is native to Asia from the Caucasus east through the Himalaya through China, Japan, and Korea. Orange daylily persists where planted, making them a very good garden plant.

Uses

The flowers, leaves, and tubers of H. fulva are edible. The leaves and shoots can be eaten raw or cooked when very young, lest they become too fibrous. The flower petals and young tubers can also be eaten raw in salads, stir-fried, or otherwise cooked. The petals seem to taste better when cooked, but can also be fried for storing, or dried and used as a thickener in soups or sauces. The cooked flower buds, served with butter, taste like green beans or wax beans. The tubers are a good potato substitute, with a reportedly "nutty" flavor.
