Epiphytes

Epiphytes are intriguing plants that grow on other plants without harming them. Unlike parasitic plants, epiphytes don’t take nutrients from their hosts; instead, they absorb moisture and nutrients from the air, rainfall, and the organic matter around them.

There are three main types of epiphytes:

- Holoepiphytes: These plants live their whole lives up in the trees, never touching the ground.

- Hemi-epiphytes: These start off on another plant but eventually grow roots that reach down to the soil.

- Proto-epiphytes: These epiphytes partially rely on their host for nutrients while drawing moisture and nourishment from the air and rain.

You’ll often find epiphytes in lush, shaded forests, particularly in tropical and temperate regions where humidity and rainfall are high. They have special adaptations that allow them to thrive without soil. For instance, many have roots covered in a spongy layer called velamen, which helps them absorb moisture from the air and rain. These roots also help anchor them securely to their host plants.

The leaves of epiphytes often form natural ‘tanks’ or ‘cups’ that catch rainwater, fallen leaves, and other organic material, which breaks down and provides essential nutrients. Some popular examples of epiphytes include:

- Anthurium

- Orchids

- Bromeliads

- Staghorn ferns

- Orchid cacti

- Bird's nest ferns

- Monstera

- Certain types of Pitcher Plants

One of the best things about epiphytes is their flexibility. They can be grown in pots or mounted in various arrangements. When potting epiphytes, good choices for soil include orchid bark, sphagnum moss, or a combination of the two.

Orchid bark is especially good because it keeps the soil light and airy, which is important for the roots of epiphytic plants. Sphagnum moss helps retain moisture while allowing airflow. There are special pots made just for epiphytes (orchid pots), but terracotta pots also work well for these plants because they allow air to circulate and help absorb excess moisture.

A special group of epiphytes, Tillandsia, can grow without soil at all. While they might have roots when you buy them, those roots aren’t their main source to get water. These plants, often called air plants, are often seen displayed in seashells, on bark, or in empty pots.
