For masses of color in your flower beds, long-blooming phlox is hard to match.
Many varieties are pleasantly fragrant, make terrific cut flowers, and attract butterflies.
But the beauty often comes with a price. By late summer, these leaves are often dying, and many of the top leaves are covered with powdery mildew as well. Resistant plants are not totally immune to disease, but they do possess characteristics that will keep the mildew from taking complete control. Both perform spectacularly and have had hardly a spot of mildew on their leaves. You can count on these sturdy varieties to anchor your garden for many years to come.
