I have this weed growing on my property. It looks like a tomato but STINKS like crazy when I pull it up. It's growing in weird places that have never had any gardening. It grows very large but stays close to the ground - it sprawls out in all directions. I'm in southern Utah where there are a LOT of noxious weeds, little rain and very poor soil. This weed is basically growing in hard-packed clay, and it flourishes. Any ideas what it is?
