- Alternate, basal, to 1m long, 3cm wide, glabrous, entire, linear. Leaves of the upper stem reduced to small bracts.
- Terminal, paired panicles.
- Perianth red-orange with yellowish base and light midrib, recurved, to +12cm long and broad, joined at base into short tube. Petals 3. Sepals 3, slightly smaller than petals. Stamens 6. Style 1.
- May - August.
- Mostly cultivated. Also found along roadsides.
- Native to Eurasia.
- This is the species from which hundreds to thousands of cultivars have been grown. Luckily the cultivated plants are sterile but they do spread by means of underground stolons and form large colonies.
This plant is extremely common on roadsides and in cultivation.
The flowers and roots are edible. Don't eat the mature leaves and stems, you'll be sorry.
"Fulva" means "orange-yellow" in Latin.

Following an earlier European introduction from Asia, Hemerocallis fulva was brought to North America in the seventeenth century. This commonly cultivated daylily, the wild type, is distinguished as cultivar 'Europa' Stout and is a self-sterile triploid producing no seed. Essentially, it is a large, complex clone. Plants persist from cultivation or have arisen from root or rhizome fragments, which are capable of plant regeneration. Cultivar 'Kwanso' Regel, another ancient garden selection, persists in many areas along with the wild type and has fully doubled flowers. In eastern Asia, both diploids and triploids occur in the H. fulva complex and have been the basis for extensive breeding and tetraploid cultivar selection (A. B. Stout 1934).
