We have this plant that looks exactly like a corn plant. Tom saw it while he was mowing the garden pasture earlier this summer. He thought it was a volunteer corn plant, so he left it standing to see if it was going to produce any corn. It's way across the field from the garden.
From a few feet away, it looked like there were a couple of ears of corn on it.
But no, it's not corn...or, not any kind of corn that I've ever seen. I guess it's some kind of weed that we don't want taking over the pasture. It's bursting with some kind of seed head, so I cut the stalks down to prevent the seeds from maturing and reseeding.
