When I bought my house, there was this blue flower growing in partial

hugging vine (but very slow-growing, maybe because of the shade/dry

Unfortunately, my well-meaning brother didn't notice it there because
it wasn't in flower and raked it up while getting ready for Halloween
trick-or-treaters! * I don't know if he got the root or not, but if I
can identify it, I'd like to plant some more... it's a charming little
plant and looks great growing over the landscaping rocks...

I've done countless web-searches, browsed most of the Lady Bird
Johnson flower database... and come up short...

I would be eternally greatful if someone could give me a clue:

It looks like a phlox to me. although not a Phlox divaricata, maybe
Phlox stolonifera -- Creeping Phlox. but these also appear to be 5-
petaled. Although not sure it can grow in Texas. A perennial.
