Blue Moon turns your garden on its head by covering the ground in countless lilac-azure blooms. These dainty 5-pointed flowers will enchant you with their colorful presence and perfume. Just as you'll love gazing at these fresh and lovely darlings, so too will butterflies and hummingbirds come to bask in the glow of Blue Moon. This hardy perennial naturalizes easily and is quick to patch over the barren spots of your yard with its appealing lacy foliage and color-packed flowers. While many Phlox are like a fitted sheet and tend to hug the ground, Blue Moon is more like a low-hanging cloud of flowers that rises to about knee level. Woodland Phlox likes plenty of shade and for its soil to be fertile and moist. A light layer of mulch also encourages healthy growth. 1 Quart Container. Zones 3 to 8.
