Zelkova (Zelkova serrata) Description:Zelkova (Zelkova serrata), commonly known as Japanese Zelkova, is a graceful, large deciduous tree prized for its attractive vase-shaped form, serrated foliage, and unique exfoliating bark. Native to eastern Asia, Zelkova is a popular choice for shade, street, and specimen planting—especially as a resilient alternative to American elm. In spring and summer, its lush green leaves provide dense shade, transforming to brilliant shades of yellow, orange, and red in fall. The smooth gray bark exfoliates with age, revealing patches of orange-brown for year-round visual interest. Zelkova thrives in urban environments, tolerates drought and pollution, and is low maintenance, making it ideal for residential and public landscapes.
