Hi, my neighbor forwarded this picture to me for ID but I can't positively ID it. It's from her friend's yard in our same general area ( Fort Worth). My first impression was some sort of wood violet but I'm not sure. She said it seems to be invasive since it's everywhere in her gardens this spring. We had an unusually cold snap here where we went below 0 Fahrenheit so that may have been a trigger for some dormant seed. Thanks in advance for your help.
