Pinus banksiana ‘Jack's Bean Stalk’

Pinus banksiana 'Jack's Bean Stalk': This is a choice, unusual Jack pine that has a clever name. It was found by Mike and Cheryl Davison who enjoy hiking and botanizing in the upper Great Lakes and in the Cascade mountains. It stands out from other Jack pine selections because it has such an incredible narrow, upright form with an irregular branching habit. Because of such branching, no two plants will conform to each other. Rather, they will assume their own unique, constantly evolving sculpture like form. Adding to their natural, artsy beauty are interesting, stiff, short, slightly curved, medium green needles that are held in bundles of two. Needles are shed after two to three years so its relatively less dense canopy allows the bones of the sculpture to readily be revealed. The combined effects of these characteristics make for quite a standout in the garden without it needing much horizontal space. In ten years, a specimen could be 4 to 10 ft. tall and 2 to 3 ft. wide.

Jack pine is suitable for USDA zones 2 through 6. Our offering is grafted onto Pinus sylvestris (Scots pine) rootstock which is adaptable to a variety of well drained soils. This bean stalk needs a sunny site.
