Hey Joe,
Here's two whips that were in the ground in Houston for 2 growing seasons. Southern exposure with partial shade midday, irrigation but otherwise ignored. Pictures after pulling and initial styling:

I wasn't blown away by the growth, but it was only 2 seasons - they perhaps doubled in thickness.
I had a lot of fun with a 45" tall prostrata. Something like that may be a good candidate if you can tolerate the foliage and it's not too humid where you are.
Hope this helps.
