Phlox divaricata

Phlox divaricata: Woodland Drift

Softly enchanting, Phlox divaricata brings a cloud of spring colour to shaded and semi-shaded spaces. This native woodland phlox forms a low, spreading mat of green foliage topped in mid to late spring with fragrant, starry flowers in pale blue to lavender tones. Its open, airy habit creates a natural drift that weaves beautifully through spring ephemerals or along woodland edges. A magnet for butterflies and early pollinators, it offers gentle charm and ecological value in equal measure.
