ACER PLATANOIDES 'COLUMNARE' Upright Norway Maple

3345 North Market, Wooster

Planted: 1961

1971 Comments: The trees are narrow columnar in habit, well-established, and have a very formal appearance. Although there is an overhead line, the trees appear too narrow for this commercial area where the buildings are set back from the street.

Upright Norway Maple

1997 Comments: Some of the remaining plants are doing poorly. These plants are beginning to broaden with age as is typical of upright cultivars. This high traffic area may impact the plants somewhat. Although the trees were formal and upright, they are now informal and spreading.

Fifty-six percent of the overall planting survived (12 of 14 trees). The 1997 data in the table are based on four trees.
