Phlox are one of those bounteous summer flowers any large sunny flowerbed or border shouldn't be without. There are several different kinds of phlox. Garden and meadow phlox produce large panicles of fragrant flowers in a wide assortment of colors. They also add height, heft, and charm to a border. Low-growing wild Sweet William, moss pinks, and creeping phlox are effective as ground covers, at the front of the border, and as rock and wild garden plants, especially in light shade. These native gems have been hybridized extensively especially to toughen the foliage against mildew problems; many recent selections are mildew-resistant. Phlox need amply moist soil for best overall health.
