I had a spot up close to the house that I thought might be a good place for some daylilies, it was up against the house but open to the East and the South, but did also get some shade from large oaks. I potted up some daylilies and tried them there this past summer. They did not do very well, not enough sun was my conclusion, but I might pot some more up in that location this winter and see if the heat from the brick might give them an advantage during the cooler season.
