Tamarisk how tall?

I have always loved these beautiful fluffy pink trees and would so love one, but I have only a small area to plant one. :(
Any ideas how tall they get and what conditions they like?
Thanks in advance.

The one I had was about 12ft. tall and growing. We have just moved house after cutting it back it's lax habit can be a nuisance but the flowering time is wonderful........

 

Thanks for your reply Chobart I'ave been very lucky as Bob took me to get one today!
