This cultivar is an upright, narrow form that was selected in 1993 by Mike Yanny at Johnson's Nursery in Menomonee Falls, Wisconsin, northwest of Milwaukee. It is slow growing like the mother species of about 2/3 foot/year, might make it to 1 foot/year with really good conditions. I discovered several young trees in a row in Harmony Hill Nursery real close to Downingtown, PA in October 2020. Looks very good!
(There has been a columnar European Hornbeam offered by the nursery trade for several decades and is somewhat commonly planted by landscape architects for municipalities in public landscapes and on various college and office park campuses. The European species turns a yellow fall color, not a really good bright orange to red. Most European woody plants do not develop as good a fall color as North American or East Asian species.)
