As Mother’s Day approaches, U.S. Customs and Border Protection (CBP) agriculture specialists urge travelers to be aware of regulations concerning the importation of flowers and plants from Mexico. At this time of year, there is typically an increase in flower imports, which can pose risks to American agriculture by introducing pests and diseases. To safeguard U.S. crops and the environment, certain flowers, plants, and soil are prohibited from crossing the border. These measures aim to prevent the spread of invasive species and plant-related illnesses that could harm crops and lead to costly containment efforts and export restrictions.
CBP specialists thoroughly inspect all flowers and plant materials entering the United States. The inspection process involves shaking the flowers physically to remove hidden insects and using magnifying glasses to detect pests or diseases. Should pests or diseases be found, they are sent to the U.S. Department of Agriculture, where experts use digital imagery and technology for accurate identification.
Roses and carnations are among the flowers permitted entry after inspection, but chrysanthemums are banned from entering U.S. passenger ports from Mexico. This restriction helps prevent harmful fungi, such as Chrysanthemum White Rust, from threatening domestic flower growers. Plants intended for cultivation must have appropriate permits, and soil from Mexico is banned due to soil-borne pest risks. Travelers must declare any plants or flowers to CBP officers upon arrival. Although harmful pests are found in only a small fraction of inspected flowers, a single invasive species can cause significant crop damage.
Bouquet fillers can also pose risks. For example, Murraya, or orange jasmine, can carry the Asian citrus psyllid, a pest threatening citrus crops. If a bouquet contains infested greenery, the entire arrangement may be seized at the border.
CBP advises travelers bringing in flowers, plant materials, and other agricultural products to consult the Bringing Agricultural Products Into the United States page before traveling abroad. To avoid penalties and prevent introducing pests and diseases into the U.S. ecosystem, travelers should declare all items acquired abroad to CBP officers. More information on restricted items is available in the Know Before You Go Guide.
