My N scale Redwood trees come as single trees and vary from 5-6" tall.   Please indicate below how many you want in medium green foliage or dark green foliage.   In photo above, the left tree has medium green foliage and the right tree has dark green foliage.   
 
Indicate below whether you want roots?    ( Yes or No )     (Trees illustrated above have roots.)   
 
These tree typically take about 3 hours to make in stages, but require multiple coatings of wood filler to hide the core.    Check out my H.O. sized Redwoods for more photos and variations.
