Status
Silktree is an invasive species of small tree that has spread across much of the United States since its introduction as an ornamental in 1745. "Silktree is a strong competitor in open areas or forest edges due to its ability to grow in various soil types, ability to produce large amounts of seed, and its ability to resprout when cut back or damaged. Silktree reduces sunlight and nutrients available to desired species because of the denseness of the stand. An opportunist, Silktree will take advantage of disturbed areas, either spreading by seed or germinating in contaminated soil. Silktree is often seen along roadsides and open vacant lots in urban/suburban areas and can become a problem along banks of waterways, where its seeds are easily transported in water (University of Florida, Center for Aquatic and Invasive Plants) ." Silktree is native to Asia from Iran through Japan.
