As Mother’s Day approaches, U.S. Customs and Border Protection (CBP) agriculture specialists at the San Diego Field Office are reminding travelers about the strict rules surrounding the import of flowers and plant materials from Mexico to protect American agriculture from pests and diseases.
Surge in Flower Imports Raises Risk to U.S. Crops
Mother’s Day weekend typically brings a rise in cross-border flower imports, many of which could carry invasive species or plant-related illnesses. These pests pose serious threats to domestic crops, potentially resulting in costly containment efforts and damage to exports.
CBP’s Inspection Process for Imported Flowers
CBP agriculture specialists closely examine all incoming flowers and greenery. The inspection includes shaking the plants to dislodge hidden insects and using magnifying tools to detect pests or signs of disease. Any suspicious material is sent to the U.S. Department of Agriculture for further analysis using digital imaging and identification technologies.
Commonly Restricted Flowers and Plants
While many flowers such as roses and carnations are typically permitted after inspection, certain species like Chrysanthemums are banned when brought through passenger ports from Mexico. Chrysanthemums can carry dangerous fungi like Chrysanthemum White Rust, a threat to U.S. flower growers. Soil and live plants intended for growing are also prohibited unless accompanied by proper permits.
Risky Bouquet Fillers May Lead to Seizures
Some greenery used in bouquets, such as Murraya (orange jasmine), can harbor the Asian citrus psyllid — a pest capable of devastating citrus crops. If one filler in a bouquet is contaminated, the entire arrangement will be confiscated.
Guidance for Travelers Bringing Plants Across the Border
To avoid penalties and help prevent the spread of invasive species, CBP urges travelers to declare all flowers and plant materials at the port of entry. More information on allowable imports can be found on the Bringing Agricultural Products Into the United States page and the Know Before You Go guide.
