Hi, I'd ike to plant such a hedge, but I'm seeing conflicting info about the mature spread of this plant. Some sites say 2-3 feet and others 3-5 feet.

I'm worried that if I plant them 2 feet apart, they'll die from overcrowding. If I plant them 4-5 feet apart there might be gaps in the hedge and no privacy.

Tips and advice will be very welcome and appreciated.
