Tall Garden Phlox are a mainstay in the midsummer sun garden, and this hybrid type will extend the color of Phlox by blooming even earlier; starting in early summer. The dark green, glossy foliage is mildew and disease resistant, an improvement on older varieties of Phlox that don’t hold up as well in the heat and humidity of summer. Plant these in an area with good air circulation and plenty of sunshine for the best performance. With a stoloniferous growth habit, this Phlox will spread slowly over the years.
