BOSTON (CBS) – The USDA identified some of the mysterious seeds that were mailed to homes around the country, including in Massachusetts, from China.

The seeds apparently include mustard, cabbage, and morning glory.

They also include some herbs like mint, sage, rosemary, lavender, and hibiscus.

For weeks, people in the U.S., Canada, and United Kingdom have been receiving seeds in the mail. All 50 states are warning people who receive them not to plant the seeds.
