Quercus mongolica, commonly known as Mongolian Oak, is a deciduous tree native to mixed forests, forest edges, and mountainous regions in Japan, China, and Korea. It can reach up to 98 feet (30 meters) in height and is known for its broad, rounded crown and sturdy trunk. The Mongolian Oak produces acorns that are a food source for wildlife and has bark that is deeply furrowed, providing a distinctive texture in the landscape. The leaves are lobed and turn a vibrant yellow to red in the fall, adding seasonal interest.

Mongolian Oak is valued for its hardy nature and adaptability to various soil types, though it prefers well-drained, acidic to neutral soils. It is often used in reforestation projects and urban landscaping due to its tolerance of pollution and soil compaction. In cultivation, it requires full sun to partial shade and moderate water, making it relatively low maintenance. This oak is also appreciated for its production of the flavono-ellagitannins mongolicin A and B, which have potential medicinal properties. However, gardeners should be aware that it can suffer from oak wilt and other fungal diseases.CC BY-SA 4.0
