You're looking at the first showing of pink phlox in late July. You'll notice that the black-eyed susans aren't out yet. In front of the phlox are a few light mauve flowers, which are false dragonheads (also known as Obedient Plant, or Physostegia Virginiana). If you have a small garden, I strongly recommend not planting these. They are very invasive, and not particularly rewarding. You should also be able to make out a black stake to the right of the phlox. That's a candle lantern which casts a really wonderful glow over the flowers and foliage during night time coffee or tea.
Earlier in the summer, the delphiniums were in bloom.
