The ditch lily is Hemerocallis fulva 'Europa', which is a triploid. The AHS database gives it, and several other triploids, as diploid for some reason, which ATP has copied, not unreasonably. I see the ATP database actually has two different entries for it:
Ditch Lily (Hemerocallis fulva)
and this one, which also has it erroneously listed as diploid:
Daylily (Hemerocallis 'Europa')
That said, while triploid 'Europa' is the "ditch lily" there are other forms of Hemerocallis fulva grown in gardens that collect daylily species and which are diploid.
That doesn't make much difference to the possible result of a "ditch lily" cross, though. To quote Maurice from another thread:
The quote is from this thread:
