Epiphytic Plants: 10 Surprising Species That Don’t Grow in Soil

When we think of houseplants, we imagine them rooted in soil. But what if I told you some of the most popular indoor plants don’t rely on soil at all? That’s right—many are epiphytic plants. These unique species grow on trees, rocks, or other surfaces, absorbing nutrients and moisture from the air and rain.

From orchids, bromeliads, and some ferns to striking climbers like Monstera deliciosa, epiphytes add diversity and mystery to gardens. Let’s explore 10 plants you probably didn’t know were epiphytic.

1. Orchids

One of the best-known epiphytes, epiphytic orchids cling to trees in tropical forests. Their aerial roots absorb moisture directly from the air.

• They belong to the cacti, orchids, aroids, lichens, moss, and ferns group.
• Stunning in homes across Canada and the USA, they thrive when mounted on bark or grown in airy orchid mixes.

My first orchid came mounted on driftwood—it looked unusual at first but grew healthier than any potted version.

2. Bromeliads

You’ve likely admired bromeliads for their vibrant rosettes. But did you know they’re epiphytic?

• Bromeliads trap water in their central cups, drawing nutrients from debris that collects there.
• They’re part of the aroid, bromeliad, cactus, and orchid families.
• Popular in tropical homes worldwide, they adapt well to bright, humid spaces.

3. Ferns

While many ferns grow in soil, some are epiphytic.

• Examples include staghorn and bird’s nest ferns.
• These ferns rely on trees for support but don’t harm them.
• They belong to the orchids, bromeliads, and some ferns family of epiphytes.

In my experience, mounting staghorn ferns on wooden plaques creates a living piece of wall art.
