Synonym : Hemerocallis citrina
Order : Asparagales | Family : Hemerocallidaceae
The name Hemerocallis derives from Greek words ἡμέρα (hēmera) "day" and καλός (kalos) "beautiful".
The flower is strictly day-opening. Opening in the morning and closing in the evening of the same day.
It is native to Asia, from the Caucasus through the Himalaya to China , Japan and southearstern Russia . 4 varieties may be recognized in China : kwanso, aurantiaca, fluva and angustifolia.
H. fluva is originally a diploid plant. Most hybrids are tetrapoids. However, the kwanso variety is a tripoid. Tripoids and tetrapoids plants cannot seed, they reproduces only by stolons and division.
In the United States and Canada , H. fluva and H fluva longituba has become an invasive species.
The flowers are edible and are used in Chinese cuisine and medicine. They are sold either fresh or dried.

Re: Breeding with triploids
I have a strong interest in unusual daylilies.
I am attaching a link for a picture of a seedling that blooms in September.
This is a picture from yesterday. It is H. Thumbergii x H. Kwanso.
It is unusual for the following reasons.
H. Kwanso is a triploid and usually sterile.
This seedling blooms until October with more than 100 blooms.
It is not rizomous so it clumps, rather than spreads.
The H. Thubergii was a seedling from Darrel Apps that
was very fertile and pods with up to 50 seeds.
The foliage is very wide and a light olive green.
The apps seedling was crossed with a melon based
lily so offspring from this should generate nice pinks and melons.
