Border Patrol is working to make sure imported Mother's Day flowers are safe. U.S. Customs and Border Protection says agriculture specialists are working at El Paso, Texas area ports of entry to make sure that both personal and commercial imports of Mother's Day flowers are fully vetted. They are ensuring that the flowers are free of insects, pests and diseases that could upset agriculture in the U.S. CBP says they strongly suggest people consult their website to see which flowers are allowed into the country. Some of the flowers that aren't allowed due to pest risk are chrysanthemums and choysia.
