i had creeping phlox for two years. Penstemon ( native) was planted nearby. Penstemon won the bee battle, and i don't recall any bees loving the phlox they way they loved penstemon. I suspect creeping phlox is purely ornamental, unlikely i will add it back to the butterfly garden.
I haven't witnessed any bees, let alone honeybees on the phlox. If there were, they went directly to the penstemon.
