Amazon.com Inc said it has banned foreign sales of seeds in the United States after thousands of Americans received unsolicited packages of seeds in their mailboxes, mostly postmarked from China.
The US Department of Agriculture (USDA) in July identified more than a dozen plant species ranging from morning glories to mustard in the bags of unsolicited seeds. It warned Americans not to plant the seeds.
According to plant experts, seeds from other parts of the world could be non-native varieties that harm commodity crops.
