(CNN) If you've received a mysterious package of seeds in the mail lately, don't plant them. Several states are issuing warnings after residents across the nation have reported receiving unsolicited packages that appear to have originated in China. The packages typically have Chinese characters on the label and contain a sealed packet of unknown seeds that some state agriculture departments say could be invasive plant species. "Taking steps to prevent their introduction is the most effective method of reducing both the risk of invasive species infestations and the cost to control and mitigate those infestations." It's unclear who exactly is sending these packages, why they're being distributed and whether the seeds are actually harmful.
