Imports of Valentine’s Day flowers through Miami International Airport have increased this year despite higher costs caused by tariffs and rising wages, U.S. officials said.

U.S. Customs and Border Protection (CBP) expects nearly 990 million flower stems to pass through the airport in the weeks ahead of February 14. About 90% of all fresh cut flowers sold for Valentine’s Day in the United States arrive through Miami, with the rest coming via Los Angeles.

Most flowers, including roses, carnations and chrysanthemums, are flown in from Colombia and Ecuador. Avianca Cargo, Miami’s largest flower importer, is transporting around 19,000 tons of flowers on 320 special cargo flights for Valentine’s Day, more than double its normal operations.

Avianca Cargo CEO Diogo Elias said red roses dominate shipments during this period, making up over half of the total imports.

Consumers, however, are expected to pay more this year. Christine Boldt of the Association of Floral Importers of America said higher prices are mainly due to tariffs imposed last year on Colombian and Ecuadorian flowers, along with Colombia’s new minimum wage.

Despite rising prices, flowers remain one of Miami airport’s biggest imports. Airport director Ralph Cutié said flower shipments rose 6% from last year, with more than a quarter arriving before Valentine’s Day.

CBP agriculture specialists inspect each shipment to prevent pests and plant diseases from entering the country, officials said.
