This plant just started growing in one of my raised beds. It is about 4 1/2 ' tall now. I was hoping if I let it grow, I could indentify it, but no luck. I am in zone 5b in Penrose, CO.
rainbowgardener just IDed this plant for me. It's velvetleaf. At least I think yours is the same plant. Like she said to me, the leaves feel like velvet.
Thank you everyone for the replies. Now that I know what it is, I will be pulling it up and putting it in the dumpster immediately! Do not want it to seed. Nest time I see this plant I will know what it is.
