Hi Janet! Thank you for your assistance.
There sure does seem to be several species of plants in the wildflower.org gallery!
the plant reminds me of goldenrod too but actually when I first saw it I thought maybe it was a milkweed, the way the leaves looked, coming up the stem alternately. I do have several varieties of goldenrod growing here.
I just went and tried to get a closer picture for you of the flower but as you see they are just about spent! I wish I could get closer---macro envy setting in again!! LOL! the little tiny flowers each has five petals and each petal curls under --- you know like when you take the edge of scissors over ribbon? -- like that.
Here I'm holding the flowers between two fingers:
