Vanderwolf’s Pyramid has a refined pyramidal form with a dense cluster of needles at the end of the branchlets. The interesting outline and branching habits stand out more when planted alone. It is very adaptable and is a low maintenance plant with few problems. Its ornamental value lies in the showy dark green and silvery-blue twisted needles. Vanderwolf’s Pyramid is a very durable tree with flexible branches that can actually be tied into a knot. It was one of only two pines that were not seriously wind burned or injured during the difficult winter of 1976-77 in Chicago.

Description and Growing Information
Flowering Period
General Description
Pinus flexilis 'Vanderwolf’s Pyramid' is a dense, broad, pyramid-shaped evergreen tree. Needles are dark green with silvery blue undersides. Bark is smooth, light grey or grey-green that may turn grey-brown as the tree matures.
Used in landscape plantings such as parks, estates, shopping centres and public areas. Has an interesting silhouette and branching habit with showy silvery-blue dark green foliage which make it a good solitary feature or in small groups as opposed to mass plantings. A handsome specimen with great adaptability; often used for screening, shade or windbreak.
Very adaptable though it grows best on rocky slopes. Prefers moist, well-drained soil and will grow well in full sun or partial shade.
Upright pyramidal form.
ID Characteristic
Attractive dark green and silvery-blue needles are in fascicles of five and densely crowded at branchlet ends. Flexible, shiny green stems can be tied in a knot.
Low maintenance with few problems. White pine blister rust, a bark disease that is usually fatal, is the biggest danger. The earliest symptoms are indistinct chlorotic spots on the needles.
