Research the variety and not just the color. Different types grow at different rates. I wanted white flowers and a fast growing plant that would be more tree and less shrub. If that's what you are looking for (but red instead of white), look for either a Dynamite or Arapaho variety. They'll grow 4-5 ft a year and get up to about 20 ft. If you are looking for a smaller plant, look for a Coral Sport or Christiana. Petite Red Imp or Mandi will give you a dwarf sized plant.
I picked up two Natechez white last year at our Houston Garden Center when they were 50% off - paid $100 for the pair. They're easily half again this size now. But that's probably too far for you to go.
