This stellar plant graced my garden for years. Tall and coIorful, it blooms for a long rosy flowerheads. Little powdery mildew. Did well in our Indiana clay and hot and humid weather. The day the deer decided it looked tasty. If you don't have hungry critters about then you must have this plant!

Purchased from Spring Hill Nursery in 2004, didn't do very well the first year as is typical with most plants I get from them, but then in 2005 it did quite well, and this year it's covered in flowers. Looks very pretty and the flower stems do quite well at staying upright. Overall a nice phlox - I just had to be patient!
