The genus name Hemerocallis "day beauty" comes from the Greek words "hemera" = day, "kallos" = beauty and is related to the short duration of each flower. Each flower blooms only for a day. One mature flower stalk produces dozens of flower buds, therefore this fact is not so serious. An older plant e.g. produces up to 500 flowers. This extends the flowering period up to four weeks. Through a combination of early and late flowering varieties it makes a flowering period of several months possible.

Daylily breeding :
The first breedings of modern hybrids had begun in the 1930s. The famous German writer and perennial breeder Karl Foerster (born 9 March 27, 1874 in Berlin, † November 1970 in Bornim) wrote in 1969: "In the kingdom of Hemerocallis-opened to us a whole new continent of flowers from a variety joy beyond all of our hunches.

Only the AHS world registers all new selections. Its European counterpart is the Hemerocallis Europe http://www.hemerocallis-europa.eu. It is a non-profit organization dedicated to promoting and disseminating the Daylily.
Even Germany employs its own group "Hemerocallis" in the Gesellschaft der Staudenfreunde (GdS) with these beautiful plants. There are currently three screening Gardens (Cottbus, Schortens and Weinheim), divided into three climate zones. Here are planted several daylily varieties by the European breeders, which were rated according to a special assessment.
