Pinus albicaulis

Typically these species grow at extremely high elevations on unsheltered ridges where they endure deep snow and high winds through the winter, which prevents these trees from growing very tall. The form of each individual tree will vary depending on its growing site; although trees planted in sheltered locations will have a dense Christmas tree shape, those growing on exposed mountaintops often look more like gnarled bushes.

Because the tops of the trees often get broken off in winter storms, these trees have developed persistent clumps of active buds that remain for decades near the base of the tree and at the base of most of the branches. If the main trunk breaks off, the tree will still have many buds all along its stem to produce new trunks. Coupled with the tight clumps of short needles, the branching pattern makes this one of the best pine species for bonsai use. Trees can easily be shaped into an ancient-looking gnarled tree with thick, twisted branches that mirrors a mature tree.

Whitebark Pines are extremely long-lived and an individual tree can survive for thousands of years. However, it is important to not overwater your trees as Whitebark Pines naturally grow in steep, rocky soils that are free draining and so don't tolerate constantly wet soil throughout the summer. If you have compact soil like clay or silt then we recommend planting on the top of a raised mound 2-3' high and 3-4' wide to provide drainage. Avoid fertilizing with fast-releasing fertilizers like manure or Miracle Grow because the roots burn easily. Osmocote is a slow release fertilizer that is suitable for low-nitrogen using plants like Bristlecone Pines. We apply half the recommended dose of Osmocote every April with good results.
