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.
Limber Pine has five needles per bundle.
