I'm finding this among my bermuda that's starting to return from dormancy. I'm finding it in my backyard just a little where I used stonewall preemergent and more in the front where I didn't use stonewall. Also a lot more on the shady side where I also didn't use stonewall. It just started sprouting up like 2 weeks ago when it got warm. I notice that it isn't growing out any runners like bermuda or centipede and the base near the ground is purple. Anyone know what it is?
