The U.S. Department of Agriculture has identified some of the plant species in bags of unsolicited seeds arriving in mailboxes across the United States. Officials have warned the, which appear to have originated in China, could be invasive plant species.
So far, however, the species appear to be innocuous. At least 14 of the seed species had been identified as of July 29, according to Deputy Administrator Osama El-Lissy of the USDA’s Animal and Plant Health Inspection Service. They include mustard, cabbage and morning glory as well as herbs like mint, sage, rosemary and lavender. He said hibiscus and roses were also found.
CBS News confirmed that residents in all 50 states have reported receiving the suspicious packages of seeds. The USDA said if you receive the packets of seeds, do not plant them and contact your state plant regulatory official.
Although the species identified so far are harmless, plant experts have warned that seeds from other parts of the world could damage crops.
