Annual. (Phlox drummondii) Deeply fringed or indented petal margins give the impression of far more than the 5 petals that are actually present. Diversity of streaks, stripes and zoning makes “Twinkles” really shine. Widest possible range of phlox colors, too! Compact plants rarely exceed 9 inches and are perfect for edging. Makes a superior container variety, when situated so that the intricate details of each unique flower can be appreciated up close.
