Phlox can be cut back to shorten the height and produce blooms at a later time.
I dead head my phlox right after first bloom and get a second flush of blooms.

THE phlox for butterflies, especially swallowtails. Some comments state this particular phlox is prone to mildew, but I haven't had any on mine; fungal diseases are endemic in my area. Very tough plant. Blooms continuously.
