Last week, when I was writing about Nandina domestica, I had touched on it's ability to become invasive, though noted that at my folks' place it hadn't become too big an issue.
Last Thursday - on Thanksgiving - our neighborhood deer demonstrated why this is the case.
It's hard to be too frustrated with the deer; the one nearest the plant is the mother of the other two. We see her all the time, easily recognizing her game leg. The poor thing has been limping around our backyard for a few years now!
