I have lots of daylilies growing in a bog bed, they stay wet year round and grow great, plus I don't have to water those. I have heard of people growing daylilies in pots and sitting the pots in plastic kiddie pools of water, I think as long as the daylilies don't get water over the crowns they love having a constant source of water at their roots.
So don't despair, it may be a blessing in disguise.
