The self-seeded cosmos
Perennial ageratum, or Eupatorium, has begun to bloom.
Gaura in white, been going all summer.
Asiatic Dayflower, Commelina communis, doing so well (thanks to the rain?)
They have more blue flowers on any given day than I've ever seen before.
Its pal, Smartweed, is doing well too. I think this is one of the most polymorphic, adaptable plants around.
And NY Ironweed, threadleaf style, Vernonia lettermannii.
