I have this plant that I put in a pot and no longer have the label. I also have an ironweed that I swear looks the same as far as the leaves go. But I know what the ironweed seeds look like and this one has seed pods that I don't find on the ironweed.
here is the plant, it's the ferny looking one in the middle
here is a closeup of the seed pods on the plant
then I picked those and here are the pictures from that
I should know this and it is driving me nuts. (and mamajack too, LOL)
