Cinnamon Curls® Dwarf Korean Birch

Betula costata ‘CinnOak’

Selected from a population of seedlings grown at the North Dakota State University Horticulture Research Arboretum from open-pollinated seed collected in 1985 from Longwood Gardens (U.S. National Arboretum Accession # NA39939; Kennett Square, Pennsylvania, USA).
Introduced by North Dakota State University Research Foundation, Dr. Todd West, breeder. Submitted by NDSU.

Dwarf compact form of Korean birch with exfoliating cinnamon brown outer bark that curls in long strips exposing the white inner bark. The tree offers this special feature at a young age, eliminating the need to wait for years to enjoy. Dark, glossy green foliage throughout the summer consistently turns to a beautiful golden yellow in fall, adding to the multi-season appeal of the tree. It shows good pest resistance and tolerance to higher pH soils. Adapted to conditions of greater cold and higher pH soils where the Betula nigra cultivars ‘Little King’ and Tecumseh Compact™ do not perform well, have chlorosis issues or not fully hardy. Grows to 9′ wide by 9′ tall. Zones 3b–6b.

Available as #6 containers from Iseli Nursery (Booth #19037).
