The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has identified 14 varieties of mysterious seeds purportedly sent from China to U.S. citizens who didn’t order them. The known varieties include rosemary, sage, mint and hibiscus. The common herbs hardly seem a threat, but APHIS maintains its warning—reiterated by all 50 states—that recipients of unsolicited seed shipments should not plant them.
