Limber Pine is native to the Rocky Mountain Region, but is a great selection for planting in the Midwest. It provides a more unique look compared to common Pines planted in the Midwest (Austrian, Scotch, White, etc.) and is resistant to commonly found diseases here in the Midwest such as Diplodia Tip Blight and/or Zimmerman Pine Moth.
Limber Pine is similar in look to White Pine with a tall pyramidal form and stepped branching structure. The needles come in bundles in of five, but in contrast to White Pine the needles are a darker green and stiff, not flimsy like White Pine needles. Limber Pine can grow up to about 20″ diameter and to about 40′-60′ tall. At maturity, the spread of the tree can 20′-30′ across.
Limber Pine grows best in USDA Hardiness Zones 3-7 and thrives in sites that are moist soil to well drained. They prefer partial shade to full sun, and can be tolerant to deer and rabbit damage. In their natural range, they are exposed to cold and windy conditions. This an excellent characteristic for a tree surviving the often cold and windy Chicago winters.
Limber Pines in their natural environment are long lived species similar to Bristlecone Pine. The oldest Limber Pine in Colorado is 1,660 years old!
