In a wonderful contrast of electric blue and snow white, our Perennial Bulb Collection Phlox David & Blue Sage creates the perfect pair in the garden. Billowy and free flowering, phlox David maintains a very full display from mid July well into September. Blue sage anchors the duo with its upright, slender stems saturated in color. Blooming through mid summer, these two varieties will put on a show for all the pollinators and visitors it will attract.
