Limber Pine

Arbor walk #72, Treekeeper ID #3697

This under-used pine, native to the western United States, is more tolerant of alkaline soils than the Eastern white pine. The dark blue green needles help this tree stand out in the landscape.

This tree is primarily found in the higher altitudes, such as the Rocky Mountains. This cultivar is faster growing than the original, and grows up narrowly, in a pyramidal shape. Its large cones are also very popular for decorative purposes.
