I was asked to copy a post I made On the Porch Swing to this one... so, here is the info in a more appropriate thread...
There's a fascinating article in the newest (AHS) Daylily Journal (Vol 78, No 1, Spring 2023) re: variegated daylilies. If you can get your hands on the article, it's brilliant! Author is Chris von Kohn and, while I am paraphrasing some of his comments (no direct quotes here) but all credit goes back to him! (Any errors are mine.)
While I was aware of some of the variegated daylilies being 'out there' somewhere, there are more than I had thought and I have only one in my gardens. As mentioned above, 'Malja' is perpetually 'sold out' everywhere (been hunting that one for about 5 years).
The article contains some interesting suggestions … for one thing, it is believed that the variegation is passed only along maternal genetics, which means pollen parent is likely not relevant but pod parent must have it.
Interestingly, Hemerocallis fulva 'Kwanso Variegata' … (which I just obtained this past year) is the only known 'species' variegated daylily. And 'Kwanso Variegata' (being triploid) is, for all basic purposes, essentially sterile. The rest are hybrids... or, more correctly, sports.
Some of those listed (with varying degrees of variegation) included in the article: 1) Abbey Dore Court (Smith 1995) was listed as being unstable, as the variegation apparently may disappear... 2) Identity Crisis (White 2011) is one of the few with variegation given in percentage of appearance, at 80% ... whereas, 3) Paul John (Howard 2018) was listed as variegation only 30% of the time.
4) Josephine Elizabeth (Dittman 2004), 5) Malja (trademark name is Golden Zebra, Malan 2007), 6) Saginaw Sweetheart (Creller 2005), 7) Spectacular Union (Tomlinson 2003) did not list percentage of variegation...
8) Should Have Zagged (Krodel 2014) was noted as the variegation being only 'intermittent'.
9) Striped Fantastic (S. Brigham 2006) was registered years ago but only recently released commercially, according to the article, and was noted as a mutation of 'Kate Carpenter' - 10) White Stripe (Mullison-Hite 1984) is one of the earliest noted.
Other variegated daylilies now beginning to appear in gardens or commercially available were noted as 'sports' ...
11) Double-Edged Sword (Grossman 2013)
12) Rocky Horror (Reed 1994)
13) Pardon Me (Apps 1982)
14) Bass Gibson (Rice 2006)
There are some unregistered seedlings now showing up, too, with variegation ... really, find a copy of the article, I am barely touching on a few points here. Some of these sports are being noted as 'stable' (holding and maintaining the variegation) - 15) Variegated Vera (a sport of Vera Bigelow) and another referred to as Lyon's Pride ... which, when used in hybridizing, only produced variegated off-spring when the pod parent showed variegation as well (noted in the previous comments of this thread).
Another variegated sport apparently only showed variegation on 'new' fans but the variegation disappears as the plant ages...
So, just a very brief synopsis of a fascinating article for all of us who have a soft spot for the variegated foliage daylilies. And with the research being conducted... and the number of sports showing up... I think variegation in daylilies is a trend we will be seeing more of in our daylily gardens... and in the very near future.
