Colombia holds the world record for orchid diversity with 4,270 registered species across 274 genera, of which 1,572 grow nowhere else on the planet, according to ProColombia and the Ministerio de Medio Ambiente, making the country not only the largest living seed bank for this plant family but the primary reference point for global orchid research, conservation, and botanical tourism.
Among those 4,270 species, Cattleya trianae, known as “Flor de Mayo” (May Flower), stands as the most internationally recognized: Colombia designated it as the national flower in November 1936, naming it after 19th-century botanist José Jerónimo Triana, known internationally as “el caballero de las flores” (the gentleman of flowers); its wide petals display yellow, blue, and red tones that echo the Colombian flag, and its endangered status makes it the flagship species for every conservation campaign the country runs.
That figure represents roughly 15% of all orchid species catalogued worldwide, and Colombia maintains the title ahead of Brazil, Ecuador, and Peru largely because of the Andean mountain range, whose altitude gradient creates dozens of overlapping microclimates within short geographic distances, from warm valley floors to cold cloud forest at over 3,000 meters, each one sustaining distinct orchid populations adapted to conditions that exist nowhere else.
The cloud forests of that same department provide the natural habitat where Cattleya trianae still grows wild, making Antioquia the epicenter of both Colombia’s orchid diversity and its most visible conservation challenge.
Antioquia concentrates a third of Colombia’s orchid wealth
Antioquia accounts for approximately 1,488 species, close to 34% of the national total, concentrated in the cloud forests of the western Andes around municipalities including Frontino, Abriaqui, and Urrao, which surround Parque Nacional Natural Las Orquídeas, a protected area of nearly 28,800 hectares that serves simultaneously as a wildlife corridor, a scientific research site, and one of Colombia’s most visited destinations for ecological tourism.
Cundinamarca ranks second with roughly 940 species, of which approximately 100 are endemic, and the department gained additional scientific attention after an Instituto Humboldt report found in 2016 that 51% of its orchid species were already under some category of threat, a figure that reflects the national pattern rather than an isolated departmental problem, since the same drivers of habitat loss operate across all of Colombia’s orchid-rich zones.
Those figures show how local ecosystems sustain irreplaceable genetic diversity under mounting climate and land-use pressure, and the living seed bank that Colombia holds today is considerably smaller than the one it held two decades ago, with illegal extraction, unregulated commercial trade, deforestation, and agricultural expansion continuing to reduce it year by year.

One conservationist’s response: 25,000 plants in the mountains of La Ceja
In March 2026, National Geographic added Daniel Piedrahíta, a 62-year-old agricultural technologist from La Ceja in eastern Antioquia, to its “33 de National Geographic” list, an annual selection of global leaders driving practical solutions to critical environmental challenges, recognizing the sanctuary he built over more than 20 years in the mountains above his hometown.
The sanctuary, called Alma del Bosque, currently houses 25,000 plants representing over 5,000 orchid species, guaranteeing the permanent flowering of more than 1,000 specimens at any given time of year, while Piedrahíta runs active seed exchange programs with communities across Latin America to reintroduce species in areas damaged by deforestation, fire, and illegal trafficking, effectively operating as a private living seed bank that complements what public protected areas alone cannot sustain.
Piedrahíta’s project began more than two decades ago as a personal obsession that started in the forests of Putumayo and evolved into a structured conservation initiative, combining botanical education, ecotourism, and scientific seed banking under one operation; Colombia Visible noted in January 2025 that Alma del Bosque represents one of the most complete private orchid collections in the country, with a species count that rivals institutional botanical gardens.
Colombia’s orchid diversity conservation
In 2025, Colombia formalized a broader institutional response when researchers from the Universidad de Antioquia, the Universidad Nacional de Colombia, the Sociedad Colombiana de Orquideologia, and the Jardín Botanico de Medellin launched a joint conservation plan to identify the most vulnerable species and prevent their extinction, with Piedrahíta’s seed exchange network representing the kind of community-level infrastructure that institutional plans consistently depend on to reach areas that research teams and park rangers cannot monitor year-round.
To this day, the gap between Colombia’s record-setting orchid count and the institutional capacity to protect it remains the central conservation tension; National Geographic’s recognition of Piedrahíta in March 2026 draws attention to that gap as much as it celebrates one individual’s response to it, and the living seed bank Colombia holds will survive long-term only if the combination of protected areas, university research, community networks, and private sanctuaries like Alma del Bosque operates as a coordinated system rather than a collection of isolated efforts.
