  • A few selections, including:
    • 'Joe Witt': a selection from the University of Washington's Washington Park Arboretum.  It was named by plantsman Dan Hinkley for the former Arboretum curator Joseph A. Witt. Two trees of 'Joe Witt' are in front of Milam Hall.
    • 'White Tigress': A cultivar that is often described as a hybrid, possibly A. davidii x A. tegmentosum; but authoritative documentation is lacking. Some consider it the most heat tolerant of the snakebark maples.
