Are you asking about Hemerocallis fulva?

The plant you're probably thinking of is Daylily (Hemerocallis fulva 'Kwanso') which is a triploid. That means it has an uneven number of chromosomes, and can not reproduce sexually, thus is can't make seeds.

So, does the true (?) ditch lily, H. fulva, also not reproduce by seed? I have some I got from a friend years and years ago which has never really increased even though she said I would never get rid of them... Confused. I planted in a driveway edge and hoped they would colonize at will. They have slowly increased, but not at all rampantly.

I am curious about the plain species also. If one bought a named cultivar, they would probably know it. H. fulva is EVERYWHERE in OH, I always assumed seeds were involved but do not know any facts to share.

H. fulva is shown in our database as diploid:
Daylily (Hemerocallis fulva var. fulva) that would mean it would have no trouble reproducing by seed. 'Kwanzo' is the triploid cultivar of that species.

The common single flowered "ditch lily" is Hemerocallis fulva 'Europa' and this is the plant that is usually referred to as a "ditch lily". Hemerocallis fulva 'Kwanso' is a double flowered daylily. Both are triploids while most daylilies are diploid or tetraploid. 'Europa' can rarely set seeds but mostly spreads by rhizomes. 'Kwanso' typically does not have normal female parts therefore it cannot produce seeds in any case, and it too spreads by rhizomes. There are other Hemerocallis fulva daylilies that are diploid, however, but those would only be encountered in garden collections and not in ditches.

Sometimes the area you live in can slow the growth of a plant. The soil could be not right, the sun could be different, daylilies of the native varieties are a great deal like a grass. Sometimes disturbing them makes them grow faster, sometimes the colonies they make slow them down. Many things could control their growth speed.
