I understand that H. fulva var. littorea is late but 'Kwanso' and H. fulva var. rosea are not particularly late where I am (also 'Kwanso' is triploid without normal female parts so can't set pods although the pollen might work sometimes). Hemerocallis multiflora flowers so late here it never gets finished before the weather turns too cold. The standard late here is 'Sandra Elizabeth' but I find Hemerocallis citrina and H. thunbergii flower fairly late also.
I don't know if anyone on the Lily Auction (for some reason not called the Daylily Auction even though it isn't for lilies) exports seeds, it might be worth a look.
I don't keep up much with who is breeding for what but it kind of makes sense to go for lates anywhere there is, or could be in time, the Hemerocallis gall midge.
