If you live in the South, chances are that you’ve seen Chinese tallow tree (Triadica sebifera). Its 60-foot presence is hard to miss.

A 2010 report by the USDA Forest Service states that tallow tree is becoming a serious threat in the Delta and could muscle out native plants and change the landscape of coastal forests of Texas, Louisiana and Mississippi.
