Home / Travel Blog / Machu Picchu: know the diversity of orchids that houses a historical sanctuary

The impressive citadel of Machu Picchu not only amazes us with its stone architecture, but it is also a wild refuge like no other. In the heart of this historical sanctuary, more than 400 documented orchid species bloom, although experts estimate that this number could reach 1,000 species hidden in its 38,448 hectares. Therefore, the unique beauty of these plants is one of the greatest attractions for those seeking to explore the great biodiversity of this wonder of the modern world.

Venturing into the geographic and global context, it is fascinating to know that the "Orchidaceae" family is the most diverse among flowering plants, covering between 25,000 and 35,000 species across the planet. In the Peruvian territory, these wonders thrive mainly in the cloud forests, located between 500 and 3,000 meters above sea level, ranging from tiny moss-like forms to huge bushes.

The fascination with orchids is not recent; in fact, the pre-Inca and Inca cultures already showed their deep admiration for them in their ceramics and detailed textiles.

Following this historical trail, the chronicler Garcilaso de la Vega, in his "Royal Commentaries of the Incas", described with amazement a flower that was common in the Vilcanota river valley called Wiñay Huayna, which in Quechua means "forever young". Inspired by this rich legacy and the floral abundance of the area, the famous archaeologist Julio C. Tello named an impressive archaeological complex inside the sanctuary with the name of Winay Wayna in the year 1942. This corner of the Andean route is today an iconic stop that reflects the living abundance of these plants.

Exploration and New Scientific Discoveries

The spirit of adventure and exploration in the jungle brow continues to yield surprising results. For instance, in the year 2015, the prestigious international magazine "Icones Orchidacearum" revealed the discovery of three orchid species completely new to science: Epidendrum ochoar, Epidendrum inca huamani and Epidendrum mormontoy.

Very significantly, these unseen species were dedicated to the very guardians of the culture in the region. Consequently, the names pay a well-deserved tribute to Gustavo Ochoa Estrada (biologist in charge of conservation), Feliciano Inca Huamán Atausinchi, and Rolando Mormontoy López (guards and conservators of the Citadel and the Inca Trail), recognizing in this way their tireless work protecting the routes.

About their Morphology and Botanical Reproduction

As you step into this wild environment, for visitors interested in observing flora, it is important to know the technical and reproductive features of these plants during their journey through the sanctuary:

Floral structure: To begin with, they are generally hermaphrodites and have bilateral symmetry. They are made up of three outer elements (sepals: two side ones and one back one) and three inner ones (petals). In addition, the lower petal, called "lip", shows an evolutionary change, being larger, with intense colors and fleshy ridges to attract pollinators.
Pollination system: Furthermore, 97% of orchid species depend on an outside vector for their reproduction. Thus, their pollen does not spread with the wind, but groups into compact masses called "pollinia".
Biological vectors: Finally, the transfer of the pollinia from one plant to the pistils of another requires the action of endemic pollinators from the cloud forest. Depending on the shape of the orchid, this amazing process is helped by flies, mosquitoes, bees, wasps, beetles, butterflies and nectar-eating birds, highlighting the vital role of hummingbirds.

Planning your visit and the blooming season

To enjoy the botanical observation in the Historic Sanctuary of Machu Picchu, it is essential to align your travel itinerary with the seasons of the flora and the weather conditions of the jungle brow ecosystem. Therefore, to ensure a great adventure, keep these details in mind:

Ideal observation season: The blooming cycle of most local species begins between the months of October and November, and it goes all the way until the month of March. Interestingly, this period matches directly with the rainy season of the region, since the increase in environmental humidity and the constant rains are the biological factors that trigger the blooming of the orchids.
Operational considerations (The second month of the year): Also, it is very important to keep in mind that during this specific month, which historically records the highest amount of rain, the Classic Inca Trail network remains closed to tourism by government order to carry out maintenance work. However, the orchids inside the Machu Picchu citadel itself or on alternative train routes do remain accessible for your exploration.
Weather equipment: So, given that the best time to see orchids happens at the same time as the rainy season, the visitor must absolutely include a light and foldable waterproof poncho or jacket in their travel backpack.

Technological tools for botanical identification

Furthermore, to complete the hike and the recognition of the different species in the sanctuary, travelers can use mobile apps specialized in botany. Photographic analysis platforms like PlantSnap, PictureThis or PlantNet allow you to scan the flower in real-time with your mobile device's camera.

Finally, the use of this software on the route gives you immediate access to the scientific name of the orchid, its botanical family, and its physical description. This completely enriches the natural exploration experience without the need to touch or handle the flora of the protected area.

Orchids in Machu Picchu

Inside the sanctuary's ecosystem, certain species stand out for their roots in oral tradition and the Andean worldview:

Waqanki: Its name in Quechua translates as "you will cry", and it is deeply linked to the local myths of the region. It usually grows in the cracks of rock formations near the citadel. In its shape, it has a single flower per stem with orange sepals and purple spots on the sides. In other areas of the country, the locals call it "rooster-rooster" because its petals look like a crest.
Wiñay Wayna: Its Quechua name means "forever young". It is a white or fuchsia species that has multiple flowers. Local tradition gives it the symbolism of vitality. Its abundance in the area gave its name to both the famous archaeological complex of the same name and the mountain pass that explorers cross during the Classic Inca Trail route.
Paradise orchid: It is one of the most common species near Machu Picchu, but it is known for being short-lived, as its flowering lasts only a few days. It has an intense pink and white color, growing between 5 and 8 flowers per stem. In traditional medicine and local beliefs, it is believed to have relaxing and stabilizing effects.
Lycaste orchid: This triangular-shaped flower grows alone on bare stems, typically blooming during the Andean summer. It has light green sepals, darker petals and an orange lip. Traditional beliefs give it properties related to the interpretation of dreams.

Other standout species on the route

During the hikes through the cloud forest (like the Inca Trail or the Hydroelectric route), the visitor will also be able to observe species with unique biological features:

Schomburgk's Epidendrum: It is one of the largest orchids in the sanctuary, growing stems that can reach up to 1.5 meters in height. Its flower is brick orange with a yellow center. To observe it, it is recommended to keep your distance, as the plant has a symbiotic relationship with ant colonies that have painful bites.
Prosthechea vespa: It is an epiphytic plant (that grows on other plants) of medium size. It is known for its long, pale pseudobulbs, decorated with clusters of brown spots that look like the pattern of a feline's fur. Although they bloom only once a year, the flowering stays intact for months, making it easier to see.
Bee orchid: On the Inca Trail route, it is mostly found in the section between Hatunchaka and Huayllabamba, with a blooming cycle from January to April. Its name is due to its evolutionary shape, the flower visually imitates a female bee to attract males of the species, thus ensuring its pollination process.
Oncidium scansor: It stands out for its bright yellow color with brown spots. Being an epiphyte, it grows attached to the trunks and branches of trees. Although it is a species listed as very difficult to grow in home environments or greenhouses, the exact humidity conditions of the Machu Picchu cloud forest allow it to grow in abundance in the wild.
