@Sooby Sue, thank you for posting the Sunset article website address in the daylily thread (Etophoj).
A search in Google Scholar with the terms xeric mesic and ecotypes will produce a list of species that have populations or ecotypes that have adapted to the different conditions of locations that are described as xeric versus mesic. It is quite possible that different daylily species or different populations of daylily species may have produced xeric versus mesic adapted plants. Since the modern daylily breeding population was originally formed from several different daylily species and plants from different populations of the same species, it is quite reasonable to expect that not all daylilies would respond in the same way (or successfully) to being immersed in water or having wet roots.
