Disagree. Think it will make a perfect hedge. I have a couple that are 5' or so tall. One I planted for somoeone is also that sort of height.
I find they are vigorous. Perfect for a hedge if pruned after flowering, viz., in early March, to allow for new flower formation the following year.
good for hedge? Tough. Evergreen, easily pruned. Pest/disease resistance. Adaptable to sun or shade.
To get to 4' I reckon 3 years
