I found a package of epazote (eep-ah-so-tay) herb seeds here in Mexico and the picture on the package looked a lot like my plants, so I bought it to add to my garden to provide cover. I looked it up on Wikepedia and the nickname is "skunk herb" for it's pungent odor. It's used for cooking and for making tea. I thought that was perfect. So if anyone asks what you got growing there, tell 'em it's epazote. It's obscure enough that they won't challenge you on the spot. And if they do check up on it, they'll see words like "skunk", "pungent" and a picture that kinda looks like weed.
