this little guy is creeping onto the sidewalk from a flowerbed. decorative plant or weed?
Looks like saponaria, not a weed generally...and I don't think it's vine-y, just leggy/needs more light.
After Googling saponaria, I do think that's what it is.
Thanks so much! I'm really looking forward to learning about all of my new plants!
Saponaria officinalis, aka Soapwort or Bouncing Bet. Has an interesting history connected with that first common name. As was said not a vine, just flopping.
