Roses and Daylilies really don't like the same growing conditions. Daylilies like a drier soil and Roses need a moist soil. Look at the tuberous roots of a daylily and contrast them to a rose's much finer root system.. Those tuberous growths on daylily roots store water while there is no such storage capability for roses. In less then ideal drainage, you may have problems with making either of them happy. Plus, daylilies will spread and need to be divided periodically. Disturbing the roots of a thriving rose is not really a good thing if it can be avoided.....Now, we come to the comments about Aunt Betty who always grew her daylilies and her roses together with great success. As a nursery owner friend of mine said: "There's always an Aunt Betty who seemingly defies the odds and grows everything opposite of the norm and is successful". So if your soil is well drained, and you plant daylilies far enough away from the rose that division won't bother it, you too might turn into an Aunt Betty.
