I have 6 different varieties of garden phlox, and this is my favorite. The color is outstanding, it blooms forever, smells great, attracts bees, humming birds and butterflies.

This is my favorite plant in the garden.
In the morning the plant is blue.
At the end of the after-noon, it turn pink.

This plant doesn't give lot of seed. This automn I could only get 6 small seeds on this hole plant! But so generous flowering at the end of July until October.
