The Yellow X Paper Birch Hybrid—A Potential Substitute for Yellow Birch on Problem Sites

Yellow x paper birch hybrids and yellow birches with common female parents were compared after 5 growing seasons in an open field. Survival of the hybrids was 91 percent compared with 64 percent for the yellow birch trees. The hybrids were from 25 to 32 percent taller than the yellow birches and had 19-40 percent greater diameter. Because this hybrid not only grows better than yellow birch but also withstands greater environmental stress , it appears suitable for planting on open or partially shaded sites where ecological conditions are less favorable for yellow birch.
