For the record I wanted to add that my Vitex tree just finished blooming. It had been blooming since early June. Bloom duration is definitely effected by rainfall. Another observation: Morning, noon or night the tree was covered with bumble bees and honey bees along with various other pollinators.
Jack, I agree about Goldenrod. 120-150 species of Goldenrod and honey bees will only work certain species.
Neil, can you take a picture of the white dead nettle? I am curious.
lazy, that looks like something you might put in your smoker.
