holly cultivars include annual bearing (of fruit),
large and bright colored fruits, good foliage and a dense habit(535).
The American Forests® National Register of Big Trees 2010
lists the three largest known American hollies. These three are similar
enough in size that they are listed as co-champions at the national level.
Of the National Champions, one resides at the Chelsea Historic Site in
Maryland and the remaining two are in Arlington and Alexandria, Virginia.
Currently at the University of Maryland, we have 160 American hollies
documented in our tree inventory. Some of the easily accessible trees
include two located in front of the Main Administration Building, two nice
specimens near Clarice Smith Performing Arts Center (CSPAC) and the tree
that is referenced as #28 in the
Campus Tree Walk near H.J. Patterson. Try
to test yourself to find the remaining 155 trees.
