I can't imagine that it's a volunteer. And if the sower of the seed was hoping for a bumper crop, well, there are only so many ears you can harvest with a single plant.
When I first saw the corn plant I was on a bicycle, phone camera back at the house. But my recent wanderings have taken me all over Reston, so on Saturday afternoon I found myself right back at the corner — the urban corn corner — where I'd spied it a few hours earlier.
So here's the little corn stalk that could. Not exactly of Midwestern proportions, but not bad for a little plant in the Virginia suburbs!
