Update in case you receive those seeds…. which have begun appearing in Oregon mailboxes:
From the OSU (Oregon) Master Gardener Program
“[Oregon Department of Agriculture] officials asked anyone who receives mystery seeds not to open them and to send the package to the Plant Protection and Conservation program at 635 Capitol Street NE, Suite 100, Salem, Oregon 97301.”
