This isn't quite a gardening question, but you all seem like the right people to ask. My (mexican) husband was out walking our dog, and located what he thinks is a wild patch of epazote. We are in the Boston area. He brought home a plant, and we've compared it with online pictures. It definitely looks the same, and smells like epazote (according to him).
Does anyone know of any characteristics of the plant that can confirm or disconfirm it as epazote? Or do you know of any related plants in the area?
I'd be VERY leery of using that without having an expert identify it. Epazote is a tropical plant, & while it's naturalized in the southwest, I'd wouldn't want to use a plant that popped up in Boston. There are LOTS of plants that look like it that aren't safe to consume.
If I were you, I'd take a sample of your plant to a local Agricultural Extension Agent (there should be at least one around you can talk to) & get an affirmative before eating your find.
