Yes, the needles are from Longleaf Pine, Pinus palustris, a native Pine to the southeastern US. The photo was taken right after installation, and shows more mulch than planned. Our client expects to let the Pachysandra ground-cover grow to the sides of the path and eventually have moss between the stones. The Pine needles are a fragrant temporary mulch in this case, but a favorite of ours as a breathable permanent garden mulch.
