Quercus castaneifolia

Common Name:
Chestnut-Leaved Oak

Description:
Quercus castaneifolia, commonly known as the Chestnut-Leaved Oak, is a large, majestic deciduous tree admired for its chestnut-like foliage and impressive stature. Native to the Caucasus and northern Iran, this oak features long, serrated, glossy green leaves that resemble those of a sweet chestnut (Castanea). In autumn, the foliage turns beautiful shades of yellow and bronze, providing seasonal interest before shedding for winter. The tree produces acorns with distinctive, scaly cups that serve as a valuable food source for wildlife.

This fast-growing and highly adaptable oak thrives in a variety of soil types, including clay and sandy soils, and tolerates both drought and occasional wet conditions. It prefers full sun and develops a broad, spreading canopy, making it an excellent shade tree for large gardens, parks, and avenue plantings. Due to its strong structure and resistance to pests and diseases, it is a great choice for long-lived, low-maintenance landscapes.
