Native to northern and eastern China, lacebark pine (Pinus bungeana) is an excellent shade tree that is low-maintenance and easy to care for. Its mottled bark sets it apart from other pine species and is especially noticeable in the winter months. Layers of green, yellow, brown, purple, and red bark stand in stark contrast to the white snow backdrop.
This species of pine is usually not as readily available at nurseries and garden centers as some other pines are, so it may require a bit of hunting around to find. It will be worth the wait though! Lacebark pines are less prone to common pests and diseases as other pines, moderately drought-tolerant, and can abide a wider range of soil acidity than most other pine species. This slow-growing evergreen is best planted in early spring. Learn how to grow these unique pine trees on your property below.

Lacebark Pine Care
Lacebark pines, also commonly referred to as Bunge’s pines and white-barked pines, are hardy in winter temperatures as low as minus 26 degrees Celsius. Generally, lacebark pine trees appreciate plenty of light and regular watering but can be classified as moderately drought-tolerant. They are low-maintenance and, once established, can be left to grow outside independently. Lacebark pine trees reach 30 to 50 feet tall in full maturity.
Lacebark pine tree bark peels gradually over time, usually starting once the tree is about ten years old. The green bark peels away in oval-shaped disks to reveal yellow-brown undertones that turn olive-brown, purple, and red over time. The resulting look is camouflage-like and provides year-round interest.
These pine trees perform best in full sun environments, so growing locations should be chosen carefully for lacebark pines. Loss of needles or stunted growth are both indicators that lacebark pines are not receiving enough light.
Like most pines, lacebark pines prefer slightly acidic soil, although lacebark pines can tolerate soils with a higher pH than most other pine species. They enjoy soils that are well-drained, and consistently moist. Lacebark pines should not be exposed to soils that are especially wet or dry for long periods of time.
Lacebark pine trees appreciate consistently moist soil, especially when they are still maturing. Lacebark pine saplings should be watered regularly until they are well-established. Once established, a lacebark pine tree usually does not require supplemental waterings and is somewhat drought-tolerant. However, during abnormally long dry periods, lacebark pine trees can benefit from supplemental waterings to help support healthy growth.
Temperature and Humidity
USDA Hardiness Zones 4-8 are best for lacebark pines, and they can withstand winter temperatures as low as minus 26 degrees Celsius. They are moderately drought-tolerant pine trees that thrive in moist, humid soil conditions, but generally tolerate a wide range of humidity conditions within their growing zones.
Lacebark pines do not require regular fertilizing. However, if desired, a light feeding in the early spring of a balanced fertilizer can help give the tree a boost.
Varieties of Lacebark Pine
There are two varieties of lacebark pine, which vary in appearance and growth habit:
- Pinus bungeana ‘Silver Ghost’: A variety of lacebark pine whose mottled bark is silvery-gray
- Pinus bungeana ‘Temple Gem’: A compact, slow-growing lacebark pine cultivator
Pruning lacebark pine trees is mainly for aesthetic purposes. Generally, lacebark pines do not require regular pruning. However, depending on the desired look, lacebark pines can be pruned into a single-trunked or multi-trunked tree. They are also exceptional trees for bonsai.
Common Pest and Diseases
Pine trees are susceptible to a wide range of common pests and diseases, but fortunately, lacebark pine trees are slightly less susceptible to most of these pests and diseases than other pine species. Keep an eye out for pests like aphids, borers, caterpillars, mealybugs, weevils, western pine beetles, engraver beetles, and red turpentine beetles; as well as common diseases such cankers, rusts, diplodia tip blight, and pine wilt. Generally, if treated properly, these pests and diseases do not affect the long-term health of the tree.
Damage by strong winds and storms actually poses a larger risk to the long-term health of lacebark pines than any common pest or disease. The bark of these pines is brittle and branches can crack easily. Single-trunked trees have stronger branches and usually withstand less damage than multi-trunked trees.
