Plant of the Month
 Common Name: Limber Pine Scientific Name: Pinus flexilis | |  |
The branches of the limber pine tree are very flexible. These trees release large amounts of sap when under stress. If you have trouble identifying the tree, look at its needles; they should be in clusters of five. Limber Pine trees are threatened by forest fires and white pine blister rust. A low-intensity fire will demolish a young stand of limber pine due to the tree’s thin layer of bark. As the tree develops, its bark becomes thicker and the trees have a greater chance of surviving low-intensity fires. White pine blister rust also threatens limber pine stands in Wyoming. It is a fungus that infects the tree’s stem leading to the eventual death of the tree. There have been efforts to find trees resistant to the rust.
