Comments: This cultivar was selected by Dr. Ed Hasselkus
at the University of Wisconsin for its borer resistance
and tolerance to heat. The bark is white and does not
exfoliate. Seedlings from this cultivar do not
necessarily show the same level of borer resistance. The
glossy green foliage turns yellow in the fall.
