About 30 volunteers spent part of Nov. 16 planting eight trees near a stone turnout along Allegheny River Boulevard in Penn Hills.

The event was a partnership between the Penn Hills Shade Tree Commission, the Allegheny River Boulevard Preservation Association and TreeVitalize Pittsburgh, an application-based program that offers trees as well as related materials and expertise to interested communities.

TreeVitalize provided four Eastern redbuds — which produce pink flowers in the spring — in addition to two European hornbeams and two parrotias for some attractive fall foliage.

According to its president, Kathy Raborn, the Shade Tree Commission has planted more than 400 trees in the municipality’s parks, traffic corridors and other high-visibility spots.
