This is spreading out all over the walk - if it's a good guy I'm moving it and if it's a bad guy I'm 86ing it.
SOLVED: friend or foe?
I'm not very good at identifying plants, but I'll take a guess. Could it be a dianthus that reseeded?
If it's a dianthus it's the dinkiest one I've ever seen. The flowers, albeit beautiful fuschia in color, are no more than 1/4". And lots of foliage, which makes me wonder if it's just a cute weed...
