Red Pine (Pinus resinosa)
This Wisconsin native grows upright and quite tall (50-80′) and does well in poor sandy soils. Not commonly used as a landscape tree but often found on older homesites where it is used as a windbreak. Needles are in clusters of 2 and are 5-6″ long. Cones are about 2″ long and 1-2″ wide.
Scotch Pine (Pinus sylvestris)
This pine species is native to Northern Europe but was commonly used throughout the American landscape. The bark is often a distinctive reddish-copper color with thin flaky exfoliation. Needles are in clusters of 2 and are 1-3″ long and twisted. Cones are about 1.5-3″ long and nearly round.
Austrian Pine (Pinus nigra)
Another non-native pine species that is commonly used in the landscape. In an open setting Austrian pine can grow quite wide with a dense canopy. Bark has a scaly gray/brown appearance with deep brown furrows. Needles are in clusters of 2 and are 3-5″ long. Cones are about 2-3″ long and narrow (~1″ wide).
