Looking for narrow fast growing evergreens for screening
I'd like to add some evergreens to a border and am looking for something narrow but one that gets tall as 30 ft (or more)- White Pine Fastigiata was suggested but I've had a hard time locating it locally. There are currently some deciduous trees and a couple of 8-10 ft junipers that we are keeping in the border. We'd like to add these evergreens in that border for winter privacy screening.
Any other suggestions for a narrow evergreen? Fast growing is important as well! We have lots of arbor vitae already and wanted something different (and taller) on this side of our property.
Thanks in advance for suggestions.
