Westinghouse Park Arboretum

On October 6, 2021, the 175th anniversary of the birth of George Westinghouse, Westinghouse Park was certified as a Level 1 Arboretum by ArbNet. As part of this process, the City of Pittsburgh Department of Forestry tagged the 33 trees shown on the map and key below. Note the two new trees at #33, both Brackens Brown Beauty Magnolias, that were planted on October 6, to celebrate the arboretum and honor George and Marguerite Westinghouse. Two Yellowwood trees planted for Arbor Day 2022 are not shown.

Westinghouse Park has more than 175 trees, representing 38 individual species. For a key and map that can help identify any tree in the Arboretum, see below.

The following lists and map based on the park’s 2020 tree survey can help you identify any of the Arboretum’s trees.
