Invasive Plant Database maintains an online database devoted to plants known to occur in or around Texas that are suspected of causing invasive problems. With the exception of the Texas Department of Agriculture list (TDA Noxious Weed List) list and the Texas Parks and Wildlife Department list (TPWD Prohibited Exotic Species) list, the purpose of this site is informational and educational and it is not intended to be a regulatory tool. Many of the species on this list are economically important horticultural plants but sometimes cause problems when they escape and establish in natural areas.
