I have this weed in my front yard which is about 50 miles south of Dallas. My yard has a mixture of brumuda and st. augustine and I have tried every southern lawn weed killer i could find to kill this stuff but nothing has worked so far. It's really kind of a pretty plant - deep green, hearty leaf and seems to want to be a thick ground cover. I was so desperate that I even spot treated with RoundUp but all I did was end up with dead spots :( I would love to finally find out what this weed is and how I can get rid of it for good Thanks for your help!!.
