Which plant is illegal to transport, sell, or propagate in Pennsylvania due to its noxious weed status?

• A. Purple loosestrife
• B. Garlic mustard
• C. Japanese knotweed
• D. Oriental bittersweet

Answer: (A)

Pennsylvania treats certain invasive plants as noxious weeds, meaning it is illegal to move them, including transporting, selling, or propagating them, in order to stop their spread. Purple loosestrife is a classic example of this designation because it aggressively invades wetlands, displacing native plants and wildlife habitat, and is notoriously hard to eradicate once established. That combination of rapid spread and ecological damage led to its noxious weed status, making any transport, sale, or propagation unlawful without special authorization. In practice, this means you should not transplant or sell purple loosestrife and should follow proper disposal methods to prevent further spread.
