We have a community garden in Salem, Ma. We have 99 raised beds on top of a tennis court surrounded by a chain link fence. This plant is growing up the fence just outside of the gardens. It is next to a marsh. There was also some wild asparagus growing nearby. We are not sure if this is rhubarb maybe?myster plant #2.jpgmyster plant #3.jpgmystery plan #1.jpg
