How to grow border phlox
The bold blocks of colour produced by border phlox (Phlox paniculata, P. maculata and P. x arendsii and cultivars ) make them stalwart of the summer garden. The tall, domed or pyramidal flowerheads are traditionally grown in herbaceous borders in clumps, but can be mixed with ornamental grasses for a more contemporary look.
