Be sure to ask them if they'll flower in a pot. They'd grow, but it's the flowering that's the spectacle.
Crepe Myrtles or Lagoestrema (sp?) are great grown as hedges or bushes too. Just need constant clipping and you can keep them manageable and the more clipping the more flowers. I love those plants and there are lots of different colours these days. Big on recycling here too, but unfortunately not everyone else is.
