Pinus bungeana: Lacebark Pine1

Edward F. Gilman and Dennis G. Watson2

Introduction

Lacebark Pine is a very picturesque multi-trunked and upright, oval tree through about age 40, then begins spreading into a flattened canopy allowing filtered sunlight beneath. The beautiful grey/green, mottled, exfoliating bark becomes chalky white on mature trees and is one of the best Pines for this character. Cultivated in the Orient for its striking bark, Lacebark Pine can be often seen on the grounds of Buddhist temples. Capable of reaching 75 feet in height, it is more often seen at 30 to 50 feet with a 20 to 35-foot spread and has a rounded to pyramidal outline when young. Those planting the tree will wait a long time to see the tree display its true virtue, for growth is slow at best. The stiff, two to four-inch-long needles are sharp to the touch, as are the light brown, two to three-inch-wide, rounded cones.

Use and Management

Locate the tree where passers-by can view the trunk character, such as along a walk or near a patio or deck. Trees have a reputation for splitting apart in snow and ice storms. This can probably be largely prevented by training newly planted trees to one central leader and eliminating weakly attached trunks and branches, but this will spoil the striking multi-trunked habit so characteristic of the tree.

Growing best in full sun on well-drained, acid soil, Lacebark Pine may tolerate soil with a higher pH but should not be exposed to soils which are excessively wet or dry. The trees are also reportedly sensitive to air pollution.

Propagation is by seed or grafting.

Pests and Diseases

There are a large number of pests and diseases reported on Pine.
