Oxydendrum arboreum: Propagation of an Ericaceous landscape tree

By Charles Stern

Originally composed 2017-03-26 for the course Plant Propagation and Hybridization, Naugatuck Valley Community College Horticultural Science Progam, Waterbury, Connecticut. Revised and reformatted 2021-03-21.

Habit and Range

The high degree of similarity between plant communities in Eastern North America and East Asia suggest that, long ago, a contiguous temperate forest ecosystem once spanned these now-distinct continents. In addition to its ornamental and agroecological value, the Ericaceous tree Oxydendrum arboreum plays a fascinating role in this ancient drama of "floristic disjunction": it's one of the only genera native to Eastern North America with no known presence in East Asia.

Today, O. arboreum can be found in woodlands from New York west to Illinois, and as far south as Florida and Louisiana. Reliably hardy to Zone 5, specimens have been observed as far north as Zone 4. Its common names include:
