A lavender crepe myrtle! I don't do pink, (at least not much in my warm colored garden) but lavenders/purples go very well. Now I will have to be on the lookout around here or ask some nurseries. That is just an awesome color Dave.
Like Paul, I just did the Google search as well and Biloxi on all the nursery sites is described as pale pink.
This site has a lot of great shots and several fall into the lavender/purple range.

(and if anyone is looking to buy online, stay clear of the Aarons Nursery, it's a clear offshoot of the dreaded TyTy nursery)
