‘Vanderwolf’s Pyramid’ Limber Pine
by June Hutson       #Hot Plants

Pinus flexilis ‘Vanderwolf’s Pyramid’, a Plant of Merit selection for 2013, is a needled evergreen. The species is native to Southwestern Canada through the Western U.S. to Mexico and is found primarily in the Rocky Mountains at elevations of 5,000 to 12,000 feet. The species name refers to the flexible branchlets and twigs. It has adapted to the St. Louis climate but is not recommended for planting south of USDA Zone 7.

The mature habit of ‘Vanderwolf’s Pyramid’ is rounded and reaches about 25 to 30 feet tall in cultivation. It has beautiful, long, twisted, silver-blue needles. It is considered to be an adaptable low-maintenance conifer with few problems. It is susceptible to white pine blister rust, which is a bark disease, but this is uncommon in Missouri. Aphids, weevils, spider mites and scale are more common pests.
