Attn April: Plant Alert
Since I know you are looking for these, and I think you are in Nashville:
Went to Gardens of Babylon today (just to look...yeah, that's it...), and I saw:
1) Garden Phlox "Laura." I don't know if this is your tall purple phlox from childhood, but thought of you.
2) Pink Cosmos. It was "mixed," so there was probably some white and light pink in there too, but it was definitely going to be the same color pink I gave you, if you need more.
