Help! I have a huge plant growing in my raised garden bed. Lost the identification marker and not sure if it's a Korean plant or American....edible or toxic. The trunk is huge and the leaves are taking over. Leaves have a fragrance but not anything I recall smelling. Taste is a bit bitter ......I assumed that would not have planted a thing dangerous then I remember this might be something j planted for mosquitos. I hate to get rid of it ifs it's actual food. Thank you
