Of the species my oldest will be Hemerocallis lilioasphodelus described by Carl von Linné - better known by his Latin name, Linnaeus - in 1753 in the opus that started it all, Species Plantarum.
I also have Kwanzo. Apparently, it was scientifically named as a variant of fulva in 1866 by the German Eduard von Regel in his magazine, Gartenflora. It hasn't flowered in my garden yet this season but It has many scapes powering up. After four years of nearly dying, it is now expanding out like a miniature universe!
Today this flowered for first time for me: Hemerocallis citrius. It was described by Eugenio Baroni, 1897. I picked this up on eBay and supposedly it came from Vietnam. Well, it was the whitest and floppiest fan I ever got. But doing fine now.
Then the next oldest is TINY PUMPKIN Hudson 1975
