Question: is phlox hard to grow?
Answer: Phlox comes in two forms – there is Garden Phlox (Phlox paniculata), which is an upright flower that grows to about three feet. Creeping Phlox (Phlox subulata), is a spring groundcover that stays green for most of the year. Both are easy-to-grow perennials that come back reliably every season.
