The Oregon Nursery Guide (www.nurseryguide.com) lists it as Betula alba a synonym
of B. pendula according to other sources. The Amer. Hort. Soc. Encyclopedia dodges
the question by giving it a listing separate from all species. Not much help I'm
afraid.

does anyone know the origin of this cultivar? Is it a variety of B. pendula or
not?
