Additional Information

A clean, trouble-free small tree, useful in intensive situations such as patios and malls, and equally interesting in naturalized plantings. Useful as a large hedge if coppiced when young. Performs well in heavy shade and tolerates periodic flooding. Difficult to transplant. Move balled-and-burlapped for best results. Sometimes called Blue Beech and Ironwood (although these are best not used).
