| Distribution | Adventive/escaped plants were first discovered in NC in 1935 at Soco Bald by H. Jennison (specimen at GSMNP), at junction of Swain, Jackson, and Haywood counties. Soon after, Art Stupka found a population on Kephart Prong in Swain County (GSMNP); this population persisted at least to the 1970s. Saplings established locally away from Blue Ridge parkway in Yancey County in 1971. Updates of these populations would be welcome. Records from 8 other counties in Mountains and Piedmont are of cultivated or planted trees.
Native of northern Europe and Asia; in N.A. frequently established in eastern Canada and the northeastern U.S. | |
