Wildflowers: What is this little purple flower?

Hi! I'm new to this forum that I found while trying to Google-identify some wildflower weeds in my yard. Can anyone help me identify this pretty little thing?

 

Solanum spp. - ie, one of the Nightshades. There are thousands.

 

Thank you lorax! It sure is pretty.

 

If the flowers are pink and the fruits red this might well be Solanum dulcamara.

 

S. dulcamara here forms a vine, though. Is yours herbaceous, KyGardenLady?
