sooby said: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).

There might be different clones available under this names. My H. fulva littorea flowers from mid August until beginning of October - a very late one here. The plant I've got named H. fulva rosea flowers from Mid July until Mid of August - both diploid and fertile. I have another fulva-like plant that was identified by Gil Stelter (Gryphon Gardens) as Margaret Perry which is also flowering from end of July to end of August. Last year I used it the first time for crossing.

My Kwanso (or flore pleno?) flowers from mid July to mid September - up to now pollinations did only work with tetraploids, but I have not seen a flowering seedling up to now.

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.
This year I've got a plant that might be H. multiflora - a very long flowering tall yellow one - hopefully it is the right one. Sandra Elizabeth was my first very late cultivar - but it usually starts at peak bloom here and seldom flowers longer than Mid of August.

Thanks for the hints to H. citrina and H. thunbergii - the first I've got last year (H. citrina baronii) but it did not flower the first year, I will try to get H. thunbergii - species are hard to find here.

sooby said: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.


A friend of mine bought seeds at the Lily Auction for some years - I will ask him if this is still working (there are rumors that a sanity certificate for seeds is needed too). And of course the gall midge issue is a good argument for later flowering cultivars!
