Pinus bungeana

Lacebark pine of Susong-dong

Pinus bungeana, commonly known as the Lacebark Pine or White-barked Pine, is a species of pine native to certain regions of China. It is renowned for its distinctive, exfoliating bark that reveals patches of white, green, and purple, making it a popular choice for ornamental purposes in gardens and parks worldwide.

Description

Pinus bungeana is a slow-growing, coniferous, evergreen tree that can reach heights of up to 15-25 meters. Its most striking feature is its smooth, patterned bark, which peels away in patches to reveal a mosaic of colors beneath. The tree has a broad, irregular crown and bears stiff, dark green needles that are grouped in threes. Its cones are ovoid, small to medium in size, and mature to a brown color.

Distribution and Habitat

Originally, Pinus bungeana is found in various provinces of China, including Shaanxi, Henan, and Gansu. It grows at altitudes ranging from 500 to 2,800 meters. The species prefers sunny, well-drained sites and is often found in mountainous regions, thriving in both limestone and acidic soils.

Cultivation and Uses

Due to its unique bark and overall aesthetic appeal, Pinus bungeana is widely cultivated as an ornamental tree. It is valued in landscape architecture for its visual interest and adaptability to a range of soil types and climates, though it does best in temperate regions. In addition to its decorative use, the tree is also planted for shade and windbreak purposes.

In traditional Chinese medicine, parts of the tree, such as the resin and needles, have been used for their purported health benefits, though these uses are not widely supported by scientific evidence.

Conservation

While Pinus bungeana is not currently listed as endangered, its natural habitats are under threat from deforestation and land conversion for agriculture and urban development. Conservation efforts are necessary to ensure the survival of this species in its native range.
