Crape Myrtle Identification

[houstonholly]

Can anyone help identify what type of crape myrtle this is? Or name a few that it could be? They are in the neighborhood, but I haven’t seen them bloom so I don’t know what color they are. I’m looking to plant some in my backyard that grow straight up like this.

That isn't it's natural growth habit, it's been hacked back and now it's suckering.
