Native to China, the Lacebark Pine is a slow-growing conifer with dramatic peeling bark. With age, these trees form multiple trunks and a sparse, flat canopy. The needles only grow at the end of the branches, appearing in small custers on groups of three (3). The bark is brown and orange and smooth on the outside but white and silver once he external bark peels away.
Pinus bungeana (Lacebark Pine)
Hardiness Zones: 4-8
Height: 10-16 meters (30-50 feet) tall, up to 22 meters (75 feet) in its native environment
Diameter: 6-11 meters (20-35 feet) wide
Growth Rate: slow, about 30 centimeters (12 inches) annually
Age: Some report one tree to be 500 years old.
Root System: rarely major surface roots
Subspecies: var. ‘Compacta’ (more compact form)
Tolerates: deer, drought (moderately once established)
Problems (major): intolerant of very dry or very wet soils
Problems (minor): susceptible to breaking from snow or ice (reduced risk of grown wth one singular trunk)
Poisonous: The resin and sawdust from the bark may cause dermatitis in some.
Soil requirements: performs best in loamy, well-drained soils in acidic soils – tolertes neutral to slightly alkaline clay and sand soils
Air requirements: intolerant of urban pollution
Watering requirement: moderate
Sun requirement: full sun
Needles: grow in pairs of 3, 5-10 centimeters (2-4 inches) long, persist up to 4 years
Cones (male): cylindrical, occur in clusters
Cones (female): up to 5 centimeters (2 inches) long, yellow/brown
Seeds require stratification: yes
Monoecious or Dioecious: monoecious
The bark, initially orange with brown patches, peels in a similar fashion to birches an sycamores. The bark underneath the initial exterior is a mix of white and silver with small patches of purple. These often grow many branches, forming a shrub-like shape. When young, these tend to have a more pyramidal shape. The canopy becomes more flattened with age.
Lacebark Pines are used as ornamental plants.
