Plant ID

[bottles]

Hey all,
I am hoping to get an ID on this plant please.
It was in the display tank at my LFS and it develops purple flowers above the water. I have some pieces of driftwood that come up to the waterline, and I was thinking of tying them on about 8" below the surface.
Thanks

Looks like hygrophila polysperma. Possibly Rosanervig variety.

Thanks Joe.
Can anyone confirm this? I looked at pics of hygrophila polysperma, but I didn't see any flowered like the plant at the LFS.
Here's their display tank,
