Cutleaf Grey Alder




            Mike's Opinion

"

This fine deciduous broadleaf cultivar was introduced circa 1860 and won the First Class Certificate in 1873. It tolerates urban conditions well and is highly recommended to anyone looking for a pyramidal tree to place along the edge of a street or driveway.
