Japanese Scholartree

1997 Comments: These plants are in 5 x 6-foot cutouts. These plants have done remarkably well considering the severity of the site. Twig extension for the plants is still around eight inches per year. These plants originated from seed that has proven to be cold-hardy. The Regent Scholartree is not cold-hardy in Ohio. Seedlings from cold-hardy parents are necessary for Ohio plantings.

Sixty percent of the overall planting survived (3 of 5 trees). The 1997 data in the table are based on three trees.
