This cutie popped up in the yard. Could you please tell me what it is?

Yup. That little (non-native) "cutie" may take over your garden, your lawn (and your life) if you don't keep a close eye on it.
It certainly has taken over mine. The flowers are so pretty, I let it be for a few years. Now it is so dense it is a full mat in my garden bed, smothering my other emerging plants.
