Acer platanoides 'Curly Lamp Post', Columnar Norway Maple

Dense clusters of somewhat curled leaves are held very close to the trunk. Forms a very narrow, upright pole of a tree. Even slower-growing than its skinny relative, 'Rezek'.  Very rare — it's a hard one to propagate.  These second-year grafts are about 7 inches tall. Mature size: 5-7 ft T x 1 ft W in 10 years...someday 15+ ft.  Minimum temperature: -20° F
