Tree of the Week

For the months of November and December, we'll be showcasing pine trees in hopes that you'll see one you might want to help you celebrate the holiday season. Enjoy!





Red Pine, Pinus resinosa Ait.

DISTINGUISHING CHARACTERISTICS: Leaves in bundles of 2, slender, 4 to 6 inches long, fairly flexible but breaking readily when bent in two. Cones 1 1/2 to 2 1/4 inches long; basal scales remaining on the twig when the cone falls, leaving a small depression in the base of the cone; scales without prickles. Bark divided into flat plates separated by shallow furrows and covered with red-orange scales.

SIMILAR TREES: Austrian pine has strongly whitened buds and larger cones that retain their basal scales when falling from the twigs. Ponderosa pine has some bundles with 3 needles and much larger cones with sharp prickles.

IOWA DISTRIBUTION: Planted throughout the state but not commonly so in the west.
