Some of my biggest, fastest growing clumps are in a border garden on the west side of my house.
Where I live, the weather and wind usually move east to west. The prevailing winds seem to push the rain all the way to the house on that side, and keep that garden well watered for me. In fact, sometimes the rain comes from the other way, which would miss that garden. On the other hand, when it comes from the east, all the rain that hits the house runs down into the border garden making it get more rain than my other gardens, which may explain why my daylilies there are doing so well.
Your weather may not be the same as mine, though. Just something to think about when you are making your decision.
