This charming wildflower creates a haze of blue in the spring atop delicately branched stems as it spreads happily in the woodland garden. Woodland phlox is an herbaceous perennial that is among the most reliable and carefree plants, producing large clusters of fragrant lavender blue flowers on 6-10" tall stems. Woodland phlox performs best in well-drained, neutral to slightly acidic soils in shade, though it will tolerate morning sun. It makes a fine companion for Iris cristata, Cypripedium parviflorum var. pubescens, Polystichum acrostichoides, Tiarella cordifolia, Thalictrum thalictroides, and most woodland wildflowers.
