How To Read a Plant Label at the Arboretum

How to Read a Plant Label

The Arboretum grounds are divided into quadrants (see the Plant Collections Map). Letters indicate the grid lines running from south to north, while numbers indicate those from west to east. To find a plant on the grounds, first consult the plant collections catalog for its scientific name and grid lcoations. Plant locations are designated by their distance north and east of the points where the grid lines intersect. For example, the Mongolian Oak below is located 58 feet north and 00 feet east of M-97.
