Phlox divaricata and P. stolonifera
My phlox stolonifera has been spectacular this year, P. divaricata not so much.
I wonder what has been everyone's experience, comparatively speaking, in what conditions are best for these two plants? I'm trying to decide why one did so much better than the other. Richer soil needed, perhaps? Does the wild sweet William need more light than creeping phlox?
