Pinus flexilis 'Vanderwolf's Pyramid' / Vanderwolf's Pyramid limber pine

Pinus flexilis 'Vanderwolf's Pyramid' is a tall-growing pyramidal selection of limber pine that flushes with green new growth that later matures with long, soft, twisted, blue-green needles. Typical of this species, the branches are extremely flexible. When young, this plant is very dense and distinctive. In order to maintain this desirable denseness, it is necessary to candle prune the new growth each spring. This plant shows robust vigor and is highly resistant to disease attacks. Annual rate of growth can be expected to be 12 to 18 inches (30 - 45 cm), making a specimen mature at 15 feet (5 m) or more after 10 years.

This cultivar originated as a seedling selected in the mid 1960s by Rein Vanderwolf, former lead propagator for Vermeulen & Son Nursery, Neshanic Station, New Jersey, USA. Rein, accompanied by Peter Vermeulen found the original plant growing in the field at George Bloomer Nursery, in Flemington, New Jersey while collecting scionwood for propagation. Rein described the new plant as "different."

This "different" plant was eventually named in honor of Rein Vanderwolf and introduced to the nursery trade by Vermeulen & Son Nursery in 1972.

I live in Zone 8b in southwest Washington - Clark County. It seems as though one of my Pinus flexilis 'Vanderwolf's Pyramid' trees has white pine blister rust. It has a thick white sap that drips down the main trunk at the mid-section along with cracked bark. Over the years I have had to remove several branches with dead needles at that mid-section. I thought this disease affected only eastern white pine, currant, gooseberry & Indian paintbrush. Recently, an arborist from Integrity Tree Compant took a look at it and said that the mid-section of that area of the tree was probably dead and should cut the entire tree down before a windstorm brings it down. Is there anything I can do to treat this tree and is it really dead at the mid-section of the trunk. Also is this disease contagious to surrounding trees and has there been any reported blister rust in the state of Washington? Thank you for your help regarding this matter.


Hi Kat, Sorry if this reply comes too late, but I wanted to share that a tree doctor has been successfully treating my white pines and Vanderwolf for this. They apply medication once ever two years. Before, several feet of all the leaders of all the trees died off every year, but not since treatment began.


Hello, at what age (approximately) was this tree planted? I live on the Olympic Peninsula and am curious about what you decided to do with this tree. I'm considering planting 3 from Monrovia.
