Pinus flexilus (Limber Pine)

Pinus flexilus is not common in our woods, but there are more of them than I originally thought, sparsely intersperced among the other conifers. Few individuals I have seen are large; most are very young plants. In some parts of North America they are afflicted with White Pine Blister Rust, a fungus for which the alternate host is Ribes, or Gooseberry. The Limbers in the Caribou area have been hit hard by beetles.

This is the largest and healthiest group I have found in our area.

Here's a close up of the group shown above. There are five stems.

Mature bark of Limber Pine is grey.

Immature bark, also gray, is bumpy.

Limber Pine has five needles per bundle.

 

The cones of Limber Pine are very beautiful and robust.
