We had sprinkles last evening and overnight, but I'm not sure that we had amounts of much more than just enough to settle the dust. We'll take what we can get, though!
Dianthus, Echinacea, several types of Asters, Shasta Daisies, Black-eyed Susan, wild Monarda, Milkweed and a few others.
Red Salvias and Cosmos are what I've thought of, so far. I do have lots of the red Monarda, but here it blooms pretty early in the season, I think. I have some red Butterfly Weed started, they just need to get out there when they'll have a chance to live.
