Hemerocallis flava - 金针/ 萱草/Daylily

Hemerocallis fluva( 金针/ 萱草/ daylily )
Synonym : Hemerocallis citrina
Order : Asparagales | Family : Hemerocallidaceae


The name Hemerocallis derives from Greek words μέρα (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.
