I got two identical plants popping up near a vernonia I acquired in a swap. I IDed the plants and they are Sweet Annie, a type of artemisia. I do like the scent, but I've heard others complain about it spreading everywhere in the garden and I thought I'd ask here if people think it's worth it. I already have purple perilla, agastache and touch-me-not impatiens that show up everywhere so I'm not very excited about anything else that might do this ad need to be ripped out. I'm inclined to play it safe and try to keep it out of my yard, does anyone have any great reasons for me to keep it?
Thanks
