Zelkova serrata, also known as the Japanese Zelkova tree, was introduced in the U.S. in 1862. The tree thrives in temperate regions and is commonly found along city streets as a shade tree because it tolerates urban conditions well. Native to Eastern Asia and Japan, the species typically has a lifespan of more than 60 years and is part of the Ulmaceae family, commonly known as the elm family. An interesting feature of the Japanese Zelkova is its honeycomb bark, which typically appears gray and brown. The trunk is short, and branches grow upright. Its leaves are considered simple with serrated edges and grow in an alternate arrangement on the branches. They are narrow, typically one to two inches long, and feel rough on top and smooth underneath. Read More
