Subject: Japanese dodder found in Houston, Texas

The U.S. Federal Noxious Weed, Japanese dodder (Cuscuta japonica), is a parasitic plant previously eradicated from South Carolina and currently listed in one northern Florida county (Plants database, http://plants.usda.gov/). This weed was recently found in a small area of Houston, Texas. There is concern that Japanese dodder is prized by an Asian-American community there as a medicinal herb (referred to as Tu Tu Zi), an association that may be related to the current outbreak. Ports have been notified to be on the alert for C. japonica seeds in herb shipments from Asia.
