Commelina, dayflower.

Got it in weedy places on my lot, but can't remember the name. Sky-blue flowers are rather rare.

a horrible reseeding nightmare.. that should never be introduced to your garden ... unless for specific reason .. of which i cant think of a good one.. lol ...

ken

Likely it's the Asiatic one.

Where was this plant spotted? Did you get a closer pic of a bloom? It could be C. erecta

I was walking a dog along a road and it was growing along the front border of a house. i couldnt tell if it was deliberate plantings or weeds

Where was it geographically?

New York Lower Hudson Valley according to previous posts.

Thank you carol23 you are correct somehow i missed that simple point😂
