Every year, a new species of plant pops up in the corner of my backyard. This year, unexpectedly, it was purple dead-nettle (also known as purple archangel). I had never seen this plant in my backyard before, and I’ve been wondering where it came from. How so much of what we see in this world is up to chance, and yet, nature persists. The green-purple plant with its pink lobed flowers is beautiful–and my cat loves it, too!
