Goldenrod Solidago spp.
A stand of Ragweed. All those little spikes are blooms and seeds.
Ragweed flowers up close, so tiny and full of pollen
Ragweed close up. Tiny, tiny blooms with very small pollen grains.
Goldenrod has large, heavy sticky pollen grains.
When I first came to south Georgia more than fifty years ago, I asked about this plant, also with finely cut leaves and was told that it was Ragweed. It didn't look like any ragweed I knew.
Later I learned it is Bidens bipinnata Spanish Needles.
Seeds of Spanish Needles are annoying when the needle-like seeds get in the dog's coat, but Bidens pinnata is a nectar source for pollinators and food for critters like Bobwhite Quail.
I flushed up a covey of Bobwhite Quail when I was out taking these pics. I got too excited to get a single photo, even when the Mama Quail was crying and flailing around in the grass to distract me from the brood.
Goldenrod, one of many species of Solidago. It isn't Ragweed. It probably does not cause your sniffles.
You could be allergic to it, likely a contact dermatitis rather than a respiratory reaction.
