Rarefind Nursery in New Jersey quotes it at 5' wide and 5' tall in 10 years. It will get taller in shade and height also depends upon soil conditions. It is fast growing and eventually it can get 12' or more in the shade and could be only 4' in full sun in poor soil.

This hardy deciduous azalea is very fragrant and is excellent for attracting hummingbirds.

Thank you Rhody...guess i need to find sun for it
