This is the first year I've had this plant pop up in my garden... and it is everywhere!! All over one side of the garden, and I can't remember if it's something I planted last year, or if it's a very quickly spreading weed (this is what I'm thinking it is)... help! I don't want to pull them all out if it's a beautiful perennial, but I also don't want to encourage it's growth anymore if it's a weed!
Pull it for safeties sake.
Sharon left a weed I had not seen in decades go to bloom in a barrel, when I realized what it was , it was too late and now I am still fighting it.
