U. S. Customs and Border Protection (CBP) agricultural specialists are working to ensure that imported flowers are pest-free.

According to CBP, among cut flowers often imported from Mexico, chrysanthemums are prohibited at passenger ports of entry due to a fungi-like plant disease that could severely impact American agriculture and floral industries. Other plants often used in bouquets may be prohibited. Roses, carnations, and many other flowers are generally permitted entry into the United States following inspection. If a traveler declares a bouquet containing prohibited flowers or greenery, it will be seized. If a traveler declares a bouquet containing permitted flowers or greenery, CBP agriculture specialists will inspect the bouquet for pests and diseases, and if no problems are found, the traveler will be permitted to keep the bouquet and enter the U.S.
