Abstract

New Zealand bittercress is reported as new to the United States. While collecting specimens to determine what Cardamine species occur in the nursery trade, New Zealand bittercress was discovered in a container nursery in Wilkes County, North Carolina. The nursery tracked the shipment of contaminated plants to a wholesale nursery in Washington County, Oregon. It was subsequently confirmed that New Zealand bittercress also occurs in a nursery in Clackamas County, Oregon, and has likely been distributed throughout the United States as a contaminant in container grown ornamental plants. Thus far there have been no reports of naturalized populations outside of container nursery crop production facilities.
