Hello, I have recently moved into a new home, I found this small garden way back in my yard it is boxed into a triangle about 3'x3'x3' with this plant growing in it and now around it. I have searched the internet to find it and have not found it. Any help would be greatly appreciated. It has some leaves that seem to be about 18" long it is also growing up so far about 3' tall. I just wanted to know if it is something that will produce a food or if I should get rid of it and plant something else there. Thanks, Amy
