Hardy Trees for the Urban Northeast:

Recommended and otherwise
Peter Del Tredici

21 October 2008
ST = street tree

These are trees that, because of their tolerance of drought, road salt and compacted soil, as well as their “moderate” size and upright growth habit, can be planted between the street and the sidewalk.


PK = park or avenue tree

These are trees that are either too large for typical street planting or too low branched. These trees are best planted in parks or along broad avenues with continuous planting strips where moisture and root development will not be restricted.


FY = front yard tree

These are trees that are generally small in stature and too low branched to be planted along busy streets. They should be planted in front yards, on the private property side of the sidewalk.
