Cultivars/Varieties

'Fargo' (Dakota Pinnacle®) - A very hardy selection out of North Dakota with a narrow, upright habit to 30' tall and 10' wide. The bark is white, and the plant has been marketed as heat/drought tolerant and borer resistant.

'Whitespire' - A form originating out of Wisconsin with white, non-peeling bark, good glossy green foliage and oval habit to 40' tall. While the plant has been marketed as being resistant to heat/drought and birch borer, testing indicates that the plant may not fare well in extreme heat. The bark also may not retain its white sheen with age.
