The South American country supplying Mother's Day flowers

So, where do these flowers come from?

The answer, by in large, is Colombia, which exports more than $2bn worth of cut flowers each year, making it the second-largest flower producer in the world, after the Netherlands. Roughly 75% of Colombia's flowers (or $1.64bn) end up the in the United States, so chances are that the stems in your recent Mother's Day bouquets originated in this South American country.

A recent article in the American Journal of Transportation, noted that in just 21 days, more than 400 LATAM Airlines flights carrying 24,000 tonnes of flowers (roughly 552 million flower stems), took off from Colombia and neighbouring Ecuador.

Colombia's modern floral export industry can trace its roots back to the Cold War. Prior to 1960s, most fresh-cut flowers in the US came from California, but they were expensive. Then in 1961, US President John F Kennedy created the $100bn Alliance for Progress initiative, which aimed to combat the threat of communism by enhancing economic cooperation between the US and Latin America. Colombia became a key focus of the administration, and one of the programme's first tasks was to help Colombia develop its agricultural industry.

Kennedy even visited Colombia's capital, Bogotá, in 1961, when nearly one-third of the city's 1.5 million people swarmed the streets to catch a glimpse of the US President and First Lady Jacqueline Kennedy Onassis. It was the largest reception JFK had while in office, and today, one of the city's densest neighbourhoods is still named Kennedy.

Things began to bloom in the 1970s when improvements in air transportation made it easier to connect Colombia's fertile soil with the booming demand for flowers in the US and abroad. Entrepreneur and floriculture hobbyist Edgar Wells, whose export company sent the first shipment of cut flowers from Bogota to Miami in 1965, once compared Colombia's flower industry to the mythical legend of El Dorado, saying: "After 400 years, the true riches of El Dorado have been discovered … a permanent source of riches for all Colombians, for all time."

In 1991, the industry got an additional boost with the passage of the Andean Trade Preference Act (ATPA), which offered many South American countries a way to import a wide variety of goods duty-free, including flowers. The country now exports billions of flowers to the US every year, and despite problematic labour practices and a dwindling work force, it still specialises in growing some of the most popular flowers found in bouquets or given as gifts – including roses, carnations and orchids.

The impressive breadth of flowers grown in Colombia is partly due to the country's unique landscapes. The countryside surrounding city of Facatativá, outside of Bogota, is a hotspot for flower farms. The area's setting on a high plain savanna in the shadow of the Andes mountains makes an ideal space for flower growing, with more than 73% of Colombia's floral production taking place here. Further north, the area around Medellín accounts for an additional 24%.

Since 1957, Medellín has celebrated its growing floral heritage with the annual Feria de las Flores (Flower Festival), which is now the biggest cultural event in the city. Known as the "city of eternal spring" because of its beautiful year-round weather, Medellín explodes with colour every August as the 10-day flower festival kicks off. The event, which takes place in downtown Medellín, features food, artists, vendors and – of course – flowers.

The festival is best known for the elaborate silleteros parade. The term silleteros, or "saddle men", refers to the practice of men carrying goods on large circular plates worn on their backs. The tradition started as a way to transport produce, goods and even people through the mountainous terrain of the Andes, however it has become synonymous with flower sellers in Colombia because of the use of these back plates to transport flowers from farms in the mountains to the cities where they're sold.

During the flower festival, silleteros create elaborate artistic floral arrangements, which often depict important historical and cultural moments with flowers and carry them through the streets on these traditional back plates.

A more common, but no less beautiful, way to experience Colombia's floral heritage is by visiting one of the many flower markets in cities around the country. For example, one of Medellín’s famous farmers' markets, the Placita de Flóres sells locally grown flowers alongside other goods and produce, as does the Mercado de Paloquemao in Bogotá. Some fincas, or flower farms, also welcome guests, so that visitors can see exactly where their favourite blooms originate, while also directly supporting the people who grow them.
