American Strawberry Bush Volunteer

Today was relatively rain-free, so I was able to weed, trim, and fertilize the rose bushes. While I was out back I noticed this huge volunteer bush at the base of a giant oak. At first, I thought that it was a Nandina, but no, it wasn't. I used google image to find that it is a Strawberry Bush. The berries are vibrant!
