The Chinese elm is a hardy elm species popular in landscaping that is resistant to many common tree diseases and infestations. Due to its undemanding and unpicky nature, it can be planted nearly anywhere, becoming a favorite for urban spaces. It is a medium-sized deciduous to semi-deciduous tree (depending on climate) with single-toothed leaves. Its most distinguishing factor is its gray and red bark, which grows together in patchwork, lace-like patterns.
Although naturalized in many U.S. states, the Chinese elm is considered an invasive species in Washington, DC, and is notorious for being a garden escapee, planting itself where it pleases. Its seeds are windborne, and its flowers have both stamens and carpels, so any single Chinese elm is capable of pollinating another, making it easy for proliferation.
