If you’re planning a visit to Costa Rica’s rainforest, you’re probably hoping to spot incredible wildlife. But what often gets overlooked is what makes all of that possible: the plants.
Walk almost any trail, and you’ll quickly see that the plants are just as unforgettable as the animals. Giant leaves wider than your arms. Trees that stretch into the canopy. Flowers shaped like lobster claws or tiny flames. Some feed monkeys. Others hide frogs. A few never even touch the ground.
The rainforest depends on them. And once you start noticing them, the forest feels completely different. Still, unless you know what you’re looking at, it’s easy to walk right past something extraordinary.
This guide introduces you to 15 unique plants in Costa Rica’s rainforest you’re likely to spot during your trip. You’ll learn how to recognize them, understand why they matter, and see how they support one of the most diverse ecosystems on Earth.
What is the Flora of Costa Rica?
Costa Rica’s flora is incredibly diverse and truly beautiful. According to Ecology Prime, the country is home to about 9,000 species of flowering plants, 800 species of ferns, and more than 2,000 types of trees.
Thanks to its tropical climate and wide range of ecosystems, such as lowland rainforests and cloud forests, plants here grow in every shape, size, and color. You’ll find everything from towering ceiba trees to tiny orchids growing in the shade, many of them found nowhere else on Earth.
Why Rainforest Plants Are Essential to Costa Rica’s Ecosystem
Rainforest plants do far more than make the landscape look lush; they’re the foundation of the entire ecosystem.
For starters, they help regulate the local climate, protect the soil, and keep the water cycle in balance. Many also store carbon, which plays a small but important role in slowing down climate change.
But their impact goes beyond the environment itself. Plants directly support Costa Rica’s incredible wildlife. They provide food for sloths, monkeys, birds, and insects. Their branches offer shelter. Their flowers attract pollinators like hummingbirds and butterflies, which help other species grow and thrive.
In places like the cloud forests and lowland rainforests, plant variety is especially important. Many animals rely on specific species to survive, and when that plant life is healthy and diverse, the whole ecosystem stays in balance.
What Plants Are in the Tropical Rainforest in Costa Rica?
Costa Rica plants come in all forms: massive trees, twisting vines, bright flowers, and more. Some are easy to spot, others blend into the forest. But each one contributes to keeping the rainforest alive.
Here are 15 plants in Costa Rica’s rainforest you’re likely to see during your visit:
1. Strangler Fig
If you come across a towering tree that looks like it’s growing on top of another, twisting its roots down the trunk, you’re probably looking at one of the most fascinating Costa Rica trees: the Strangler fig.
Costa Rica is home to several species of strangler fig, also known as the golden fig or higuerón. These trees start life in the canopy, sprouting from seeds dropped by birds or bats. From there, they send roots down toward the ground and branches up toward the sun, slowly wrapping around a host tree.
Over time, their roots form a thick, woody lattice that can completely surround and eventually replace the original tree, often leaving behind a hollow core.
But beyond their dramatic structure, strangler figs are vital to the ecosystem. Their fruit feeds monkeys, toucans, and bats, and their tangled roots provide shelter for small animals and insects.
2. Heliconias
Heliconias are the most common class of flowering plants in the country, and several species grow wild throughout Costa Rica.
While they’re cultivated around the world for landscaping and floral design, in Costa Rica, they thrive naturally in tropical forests, especially along the edges of trails and near rivers where there’s sunlight and moisture.
But their beauty serves a purpose. Heliconias are a favorite food source for hummingbirds, which feed on their nectar and pollinate the plants in return. In fact, some species of hummingbirds have even evolved beaks specially shaped to reach inside specific types of heliconia flowers.
So, if you see one of these vibrant blooms while hiking, take a closer look. You might catch a hummingbird in action!
3. Bromeliads
If you’re walking through the rainforest and notice bright, spiky plants growing straight out of tree trunks, those are bromeliads. Costa Rica is home to over 2,000 species of them, making it the richest region for bromeliads in Central America.
Most bromeliads in Costa Rica are epiphytes, or “air plants,” meaning they don’t root in the soil. Instead, they attach themselves to trees (especially the massive ceiba) and pull moisture and nutrients from the rain and humid air.
You’ll often spot them in rainforests and higher-elevation cloud forests, like those near Monteverde. Many have brightly colored bracts and thick, waxy leaves arranged in a spiral rosette. That rosette collects water, forming a miniature pool that provides a home for insects, frogs, and even tiny aquatic organisms.
4. Epiphytes
When hiking through the rainforest, don’t forget to look up. Some of the most interesting plants aren’t rooted in the ground; they’re perched high above your head.
Epiphytes, often called “air plants,” are some of the most fascinating plants in Costa Rica’s rainforest. They attach themselves to trees or branches and absorb moisture and nutrients from the air, rain, and organic debris. With a humid climate and dense tree cover, our country offers ideal conditions for them to thrive.
You’ll find orchids, mosses, ferns, lichens, and bromeliads growing high in the canopy or along mossy trunks. Though they may seem like freeloaders, epiphytes don’t harm their host trees. In fact, they help create small habitats by holding water and offering shelter to frogs, insects, and even tiny birds.
5. Orchids
Orchids are everywhere in Costa Rica: on trees, tucked into moss, and even growing wild along hiking trails. And once you spot one, it’s easy to see why they’re considered some of the most beautiful flowers in the world.
Costa Rica has over 1,300 species, some of which are tiny and no bigger than a thumbnail. Others bloom in bold colors with shapes that almost don’t look real. You can catch them in the wild, especially in rainforest and cloud forest areas, or visit one of the country’s orchid gardens.
Pollinators vary; bees, wasps, flies, and even hummingbirds help keep these flowers going. And if you’re visiting between January and April, keep an eye out for Guaria Morada (Guarianthe skinneri), Costa Rica’s national flower. It has soft purple-pink petals and a shimmer that almost looks like it’s glowing.
6. Ferns
You’ll see ferns just about everywhere in Costa Rica’s rainforest, from the forest floor to the trunks of towering trees. In fact, there are around 825 species of fern growing wild here, and they come in all shapes and sizes.
One of the most fascinating is the resurrection fern, named for its ability to survive long, dry spells. When there’s no moisture, it curls up, turns brown, and looks completely dead. But once the rain returns, it springs back to life, bright green and fully open, almost like nothing ever happened.
Costa Rica is also home to eight species of tree ferns, including the leather leaf fern and even one variety with tiny bristles along its fronds. Some even reach over 12 meters tall, with thick trunks and a crown of fronds that looks like a living umbrella.
7. Cecropia Trees
When you see a tall tree with wide, hand-shaped leaves and maybe even a sloth or two, there’s a good chance you’re looking at a Cecropia.
These trees are some of the most recognizable silhouettes in Costa Rica’s rainforest. With their tall, skinny trunks and umbrella-like leaves, they often stand out along the trail or outlined against the sky. In Central America, they’re commonly known as guarumo, but you might also hear names like trumpet tree, snakewood, or even tree-of-laziness (a nod to how often sloths are found hanging out in their branches).
Their leaves are a favorite food for sloths, and their hollow stems often house biting ants, which help protect the tree from herbivores.
On top of that, Cecropias grow fast and thrive in sunlight, which is why you’ll often find them near forest edges or in clearings where light reaches the forest floor.
8. Bougainvillea
You won’t have to venture deep into the rainforest to spot this one: bougainvillea is one of the most popular flowering plants in Costa Rica’s gardens and farms. Native to South America, this colorful, thorny vine climbs walls, fences, and trees, bursting into shades of fuchsia, red, purple, pink, orange, and white, sometimes all on the same plant.
People love bougainvillea not just for the color but for the timing. It blooms almost year-round, especially during the dry season, adding a splash of brightness when many other plants go quiet.
And in rural areas, it’s not just the humans who enjoy it. On farms, chickens have been known to roost in bougainvillea vines to sleep safely off the ground.
9. Bijagua
This broad-leafed plant is easy to spot in Costa Rica, especially in the Caribbean region, where it grows along roadsides and in home gardens. It’s also called the Cuban cigar plant thanks to its tall, upright flower bracts.
The leaves are what really stand out: large, paddle-shaped, and waxy, they’ve been used in traditional ways for generations. Indigenous Costa Ricans once wrapped tamales and cooked fish in them over coals. Even today, some field workers use the leaves to bundle up their lunches before heading to work.
The plant is so common that it even lent its name to Bijagua de Upala, a town in northern Costa Rica. So if you’re driving through the countryside and see tall plants with wide, elegant leaves, chances are you’re looking at bijagua.
10. Wandering Jew
The Wandering Jew (known in Costa Rica as cucaracha) can pop up almost anywhere. It spreads easily wherever it touches the soil, growing as a thick groundcover or climbing up walls, fences, and even trees. You’ll also see it in hanging baskets or spilling out of planters near homes.
For many Costa Ricans, this plant brings back memories. It’s common to hear that grandmothers used to grow it in old buckets around the house, not just for decoration, but for its practical uses too. Traditionally, its leaves were used as natural remedies to help with gastritis, skin rashes, cuts, and even to regulate menstruation.
Today, you’ll still see it in gardens, patios, and rural areas across the country.
What Are the Healing Plants of Costa Rica?
Beyond their beauty, many of Costa Rica’s native plants have long been used for healing. Passed down through generations, local knowledge combines indigenous traditions with everyday remedies.
You’ll find some of these plants growing wild along trails while others pop up in home gardens or old coffee cans on rural porches. They’re part of the landscape, yes, but also part of daily life.
Here’s a closer look at a few of Costa Rica’s best-known healing plants:
1. Jackass Bitters
It may not have the most flattering name, but Jackass Bitters is one of our country’s most respected traditional healing plants. This tall, slender shrub topped with small yellow flowers can grow up to three meters high and is known for one unmistakable trait: its extremely bitter taste.
Indigenous peoples in Costa Rica have used it for generations to treat parasites, liver conditions, and wounds. The leaves are often brewed into tea to cleanse the body internally or dried and crushed into a powder for topical use. Mixed with herbs like basil, the powder becomes a poultice that’s applied to infected wounds or open sores.
2. Vainicillo
Known locally as vainicillo or “little vanilla,” this bright yellow-flowered shrub grows all over Costa Rica and much of Latin America. It’s easy to spot thanks to its trumpet-shaped blooms, and it’s been valued for centuries as a natural remedy.
Traditionally, we have used teas made from the leaves, flowers, and sometimes even the roots to treat diabetes, kidney problems, and rheumatism. It’s still common to find people in rural areas boiling the plant to make herbal infusions.
3. Cilantro
In Costa Rica, cilantro is part of everyday life. You’ll find it in the kitchen, in the garden, and even in homemade remedies. It’s one of those plants we always have on hand for seasoning food and for helping with digestion when the stomach feels a bit off.
Most of us grew up drinking cilantro tea for gas or stomach pain. It’s also used to help cleanse the kidneys and flush out excess fluids, something many people still believe in, especially in the countryside. It’s simple, reliable, and always growing somewhere close by.
4. Aloe Vera
Aloe vera is one of those plants you’ll find in gardens, patios, and even along the edge of a driveway in Costa Rica. With its thick, spiky green leaves and cooling gel inside, it’s long been part of daily life, especially when someone gets a sunburn, bug bite, or minor cut.
For generations, indigenous communities and local families have used aloe to treat burns, wounds, dermatitis, and other skin conditions. Some people even eat the pulpy flesh, rich in vitamins, antioxidants, and enzymes, or prepare it as a cleansing tonic to support digestion.
5. Dormilona
You’ll find dormilona growing low to the ground in many parts of the country, especially in warm, open areas. The name means “sleepy lady,” and once you touch it, you’ll see why; its feathery leaves curl up instantly as if the plant were shy or resting.
But this plant’s reaction to touch isn’t the only reason it’s known for calm. Dormilona has been used for generations as a natural sedative. Indigenous peoples in Costa Rica have long brewed its leaves into teas and tinctures to treat muscle spasms, nerve pain, anxiety, and insomnia.

Tips for Enjoying the Flora of Costa Rica Without Harming It
One of the most memorable parts of walking through the rainforest is discovering the plants up close. But with so much natural beauty around, it’s important to remember that these ecosystems are fragile. That’s why the way we move through them matters.
Take a look at these simple tips from our team for admiring the plants without harming the forest:
- Stick to marked trails: Leaving the path can harm moss beds, seedlings, and fragile roots hidden beneath the surface.
- Look with your eyes, not your hands: Many plants are sensitive, and touching them can bruise leaves, strip protective coatings, or transfer oils that harm them.
- Don’t pick flowers, leaves, or seeds: Even a small piece is relevant to the forest’s balance, feeding animals, helping plants reproduce, or holding soil in place.
- Watch your step: Roots, shoots, and tiny ferns grow near the trail’s edge. Step carefully to avoid crushing them.
- Keep your distance when photographing: Use your zoom instead of stepping into the undergrowth or leaning on trees. Find tips to photograph Costa Rican wildlife the right way!
- Teach others by example: If you’re exploring with family or friends, share these tips! It’s one of the easiest ways to protect the forest for future visitors.
