The Society of Municipal Arborists (SMA) has voted Zelkova serrata ‘Musashino’ the 2016 Urban Tree of the Year. The yearly selection must be adaptable to a variety of harsh urban growing conditions and have strong ornamental traits. It is often a species or cultivar considered underutilized by urban foresters. The SMA Urban Tree of the Year program has been running for 20 years, and recent honorees include yellowwood (2015), ‘Vanessa’ parrotia (2014), and live oak (2013). You can see the full list of past winners on the SMA website, www.urban-forestry.com.
Zelkovas are native to Japan, Korea, and Taiwan. J. Frank Schmidt & Son Co. introduced Zelkova serrata ‘Musashino’ to the North American nursery trade in 2000. Named after a city in Tokyo (which itself is a city but also a prefecture containing multiple other cities), ‘Musashino’ has been a successful and popular street tree for many more years in Japan, proving itself useful as a narrow, upright form of zelkova. It has the genetic potential to reach 45 feet (14 m) in height and 15 feet (4.6 m) in width at maturity. It is hardy in USDA Zones 5 to 9.
