An epiphytic plant is a type of plant that lives on another plant or object, using it as a support to grow. While it is not directly parasitic, as it does not take nutrients from its host, it is still able to extract moisture and nutrients from the air or rainwater that is available. Epiphytes can be found in many different forms, with some being related to specific substrate types, such as the platycerium, which grows on trees or rocks. Others, like the anthurium, can be successfully grown on a mount or in a pot.
Epiphytic plants have adapted to live in a variety of environments, including tropical rainforests and even in our own homes. Some epiphytes, like the usneoides, can grow as long white hairs, while others, like the triangle agave, feature huge rosette leaves. One of the key adaptations that allow these plants to grow as epiphytes is the development of specialized roots. These roots help the plants to anchor themselves to their host and also absorb moisture and nutrients from the air. They are often covered in a layer of suberin, which helps to protect them from excessive moisture and provides a barrier against pathogens.
Epiphytic plants, although not necessarily reliant on the ground, still need a source of water. In their natural habitat, they may receive water through rain or by collecting moisture from the air. However, in our homes, we need to provide them with regular watering. It is important to remember that epiphytes do not want to sit in a pool of water, so a well-draining substrate is essential. There are also special epiphytic solutions available that can help simulate the natural environment these plants are used to.
Epiphytes are a fascinating group of plants and can add beauty to any space. Whether you are looking for a bold statement piece like a platycerium or a delicate bloomer like an orchid, there is an epiphytic plant out there for you. So, next time you see a vibrant green ball of leaves growing on a tree or a rock, remember that it is an epiphyte, making the most of its environment and adding to the diversity of the plant kingdom.
Plants 101: Epiphytes and Air Plants
Epiphytes and air plants are a fascinating order of plants that have adapted themselves to grow not in the soil, but on other plants or objects. Unlike parasitic plants that rely on their host for nutrients, epiphytes do not harm their host and instead gather all the essential nutrients they need from the air, rain, and dust that surround them.
Epiphytes can be found in various regions and habitats, including tropical rainforests, deserts, and even in the extreme conditions of tepuis – towering tabletop mountains found in South America. In fact, it is estimated that nearly every species of plants has at least one epiphytic variety.
The effects of these epiphytes on their hosts is likely minimal, if any, and may even help the host plant to retain moisture and reduce temperature stress. Scientific studies have also shown that some epiphytes can aid in the removal of pollutants from the air, making them beneficial both in natural ecosystems and in indoor gardening spaces.
One well-known class of epiphytes is air plants, scientifically known as Tillandsia. Air plants are a variety of bromeliad and can be found in a wide range of shapes, sizes, and colors. One example is the Tillandsia amazonica, featuring beautiful green leaves that are derived from the air.
Air plants have successfully adapted to grow without soil by deriving their nutrients from the air. They can be grown indoors or outdoors, as long as they are provided with the right conditions. One popular method of growing air plants is by mounting them on a variety of objects, like driftwood or stones.
Another well-known example of an epiphytic plant is the staghorn fern (Platycerium). Staghorn ferns have large leaves that resemble antlers and are commonly found growing on trees. They are known for their absorptive abilities, using their leaves to gather water and nutrients from the air.
In summary, epiphytes and air plants are unique forms of plants that have adapted themselves to live in a different way than most other plant forms. They have evolved different adaptations, such as peltate leaves or rosette forms, to survive in various environments. Their ability to grow without soil and gather nutrients from the air make them fascinating subjects for both scientific study and gardening pursuits.

Like succulents, epiphytes are not necessarily related to one another and many unrelated plants are epiphytes
Remember, “epiphyte” refers to the growth form, not the relatedness of these plants. Epiphytes are a type of plant that grow on the surface of other plants or structures. They do not take nutrients from their host in a parasitic manner, but rather use them as a support system. This unique growth form allows epiphytes to thrive in a variety of environments, including forests, deserts, and even in indoor settings as houseplants.
Epiphytes can be found in many different plant families, including orchids, bromeliads, ferns, and cacti. Each of these plant families has evolved unique adaptations to living as epiphytes. For example, orchids are known for their beautiful flowers and aerial roots, which dangle in the air and absorb nutrients and moisture from the surrounding environment. Bromeliads, on the other hand, have specialized leaves that form a cup-like structure, which collects rainwater and provides a habitat for other organisms.
Epiphytes have developed fascinating strategies to obtain water and nutrients in their aerial environment. Some epiphytes have specialized structures, such as trichomes or scales, on their leaves that help them capture moisture from the air or absorb it from dew. Others have adapted to absorb water and nutrients from rainwater that collects in their leaf cup or in the crevices of their host plant.
Epiphytes have also developed unique methods for anchoring themselves to their host plant or structure. Some epiphytes wrap their roots around a tree branch or anchor themselves to tree bark using specialized structures called holdfasts. These adaptations allow epiphytes to withstand strong winds and other environmental stresses.
In terms of light requirements, epiphytes have adapted to survive in situations where direct sunlight may be limited by the canopy of the forest or the structure they are growing on. They are able to capture and utilize the available light by positioning their leaves or pseudobulbs in a way that maximizes photosynthesis.
Epiphytes have also developed adaptations to conserve water. The leaves of many epiphytes are covered in a waxy substance called suberin, which helps to reduce water loss through evaporation. This adaptation allows epiphytes to survive in environments where water is scarce or where drought conditions occur.
In conclusion, epiphytes are a diverse group of plants that have adapted to an epiphytic growth form, allowing them to live in a variety of environments and to utilize surfaces other than soil as a substrate for growth. Whether growing in a tropical rainforest, on the side of a tree trunk, or in a pot in our own homes, epiphytes have captivated botanists and enthusiasts alike with their unique and beautiful adaptations.
Epiphytes
Epiphytes are plants that grow on the surface of other plants, such as trees or rocks, without deriving nutrients from the soil. They can be found in various ecosystems, including tropical rainforests and temperate forests. Epiphytes have adapted to this unique lifestyle by developing specialized structures and mechanisms to obtain water and nutrients from the air or rainwater.
Some well-known examples of epiphytes include orchids, bromeliads (such as pineapples), ferns, and mosses. These plants are able to attach themselves to their host plants without causing any harm, and they often use their roots or specialized structures like aerial roots to anchor themselves.
Epiphytic plants have evolved various strategies to thrive in their environment. For example, some epiphytic orchids have developed a ball of spongy tissue called a “velamen” that absorbs and stores water for long periods of time, allowing them to survive during dry periods when rainwater is scarce.
One common misconception about epiphytes is that they are parasites, taking water and nutrients directly from their host plants. However, epiphytes are not parasitic. They only use the host plant for physical support and do not take any resources directly from it.
Epiphytes are particularly common in tropical rainforests, where the humidity and temperature levels are ideal for their growth. The dense canopy of trees provides them with a shaded and moist environment, which is perfect for their survival. In fact, most orchids, ferns, and bromeliads found in the rainforest are epiphytic.
Epiphytic plants have also found their way into human cultivation. Many orchids and bromeliads are popular houseplants, thanks to their beautiful and often fragrant flowers. People have learned how to care for these plants in a terrestrial environment by providing them with the necessary humidity, light, and nutrients.
Overall, epiphytes are fascinating plants that have adapted to an incredibly diverse range of environments. Whether they grow on trees in the rainforest or on rocks in arid regions, epiphytic plants have found ingenious ways to survive and thrive without relying on the ground for nutrients. They are a testament to the incredible resilience and adaptability of nature.

Above the Amazon rainforest, these fascinating plants grow. Known as “epiphytes,” they take their nutrients from the air and other sources instead of the soil. One example of an epiphyte is the bromeliad, such as the Tillandsia amazonica. Without the need for a trunk or classic roots, these plants thrive on the light and air in our jungle home.
Similar to the anthurium and certain ferns, epiphytes attach themselves to trees without being a parasite. They use their absorbing roots to take in water and nutrients from the surrounding natural matter. This unique method of obtaining resources allows them to form beautiful rosette shapes and grow in various sizes.
Unlike other plants, epiphytes do not necessarily follow the rules of how plants should grow. They find their home in the triangle between light, air, and water. Instead of a typical soil substrate, they may use moss or even the bark of a tree as their base. This further enhances their ability to absorb nutrients and water from their surroundings.
Epiphytic plants, including the orchid and bromeliad, have evolved special mechanisms to help them thrive in their unique environment. For example, they may produce enzymes that break down organic matter and convert it into a usable form for themselves. This adaptation allows them to survive and flourish in the treetops without direct access to soil.
In British English, the word “epiphyte” comes from the Greek words “epi” meaning “on” and “phyton” meaning “plant.” It is related to the term “epiphytic,” which describes plants that grow on other plants. UFIFAS Publications offer further information on these fascinating plants, featuring articles and resources related to epiphytes and their care.
If you have an interest in epiphytic plants or want to learn how to keep these unique forms in your house, UFIFAS Publications can provide valuable insights and advice. Discover the beauty of these true “air plants” and explore how they can enhance your living space.
