Quick Overview:

‘May Breeze’ woodland phlox is a spreading, native wildflower which forms mats of foliage with stems typically reaching 12-15″ tall. As the common name suggests, this is a woodland species which occurs in rich woods, fields and along streams. Loose clusters of slightly fragrant, tubular, pale blue flowers (to 1.5″ wide) with five, flat, notched, petal-like lobes that appear at the stem tips in spring. Stems are both hairy and sticky. Lance-shaped to elliptic leaves (to 2″ long). Can form large colonies over time as leafy shoots spread along the ground rooting at the nodes. Although the flowers on this selection are described as pale blue, it reads as white in the garden.


Best grown in humusy, medium moisture, well-drained soil in part shade to full shade. Prefers rich, moist, organic soils. Appreciates a light summer mulch which helps retain moisture and keep roots cool.  (Courtesy of Missouri Botanical Gardens Plant Finder)
