How to Grow Peperomia Plants

Peperomias have been a favorite plant for generations of houseplant lovers. We have tips on how to grow different peperomia varieties and identify which peperomia plant you have.
As the popularity of peperomias continues to grow there are more species available than ever in an incredible variety of colors, leaf forms and textures. Peperomia sizes and forms can range from bushy or trailing, to upright or cascading, providing lots of options for choosing a peperomia to suit your décor and growing space.
Peperomia plant care is easy, making them a good choice for anyone new to growing houseplants, anyone short on time, or for those who tend to be forgetful about tending to their plants’ needs.

Where do Peperomia Plants Grow in Nature?

The majority of peperomia species are found growing throughout South and Central America and Mexico. Different species have adapted to different growing conditions.

Some peperomia are epiphytes, meaning they grow in the nooks of trees or in rock crevices, getting moisture from rain and nutrients from organic matter that accumulates around the plant. The epiphytic peperomias are found in tropical forests with warm temperatures and high humidity.

Some peperomia varieties are adapted to the higher, drier altitudes of mountains. These tend to have characteristics typical of a succulent plant, with leaves and stems that have some ability to store water.
Lastly, there are a few peperomia species that grow from tubers. They have the ability to survive periods of drought by reducing their foliage and relying on water stored in their tubers. Foliage returns later with the rainy season.

Why are Peperomia Called “Radiator Plants”?

Peperomias as a group are often referred to as “radiator plants”. This common name came from the American horticulturist, Liberty Hyde Bailey (1858-1954), and was based on the unique growing environment created around radiators situated near windows. In the early twentieth century, many homes were warmed by steam-heated radiators. As growing plants indoors grew in popularity, people realized that a windowsill near a radiator provided an ideal location for growing peperomias as houseplants.

Identifying Popular Peperomia Varieties

There are over a thousand species of peperomia found in nature, but some types are more popular for growing as houseplants. Here are 22 of the most common peperomia types and varieties you might find at your local garden center or plant shop.

1. Beetle Peperomia

Peperomia angulata (Syn. P. quadrangularis)

Origin: West Indies, Panama, northern South America.
Features: Peperomia angulata is beautiful trailing from a hanging basket or a pot on a shelf. Beetle peperomia is a slow grower so you don’t have to worry about it overwhelming a space. This species thrives in humidity so rooms such as a bathroom or kitchen are good locations.

Peperomia Flowers

If you lined up all the different species of peperomia plants side by side, you might think they aren’t related at all because each plant can have such a unique look. Although peperomia plants come in a wide assortment of leaf shapes and colors there is one thing they all have in common – their flower form. Sometimes called a “rat tail” the flower spike produced by a peperomia plant is called an inflorescence. The inflorescence is covered with tiny, barely visible flowers.
When flower spikes appear (typically in the spring) it’s a sign that your plant is happy and getting all its needs met. Even though the peperomia flowers aren’t showy, they are interesting. You can leave any flower spikes that appear on your plant until they wilt naturally or snip them off at the base of the flower stem to remove at any time.

Houseplant Peperomia Care

What’s the Best Light Level for Peperomia Plants?

Peperomia plants enjoy bright, indirect light. This isn’t a plant you want to put on a sunny, southern or western windowsill as too much direct sun can burn the leaves. A couple of hours of sun in the morning or late afternoon should be safe though. Peperomias are not considered low-light houseplants; they do need bright light to stay healthy. Placing a Peperomia no more than a foot away from (but not in) a sunny window would be ideal.

How Much Water Do Peperomia Plants Need?

Try to water your peperomia beneath the foliage, right at the soil surface, to avoid getting the leaves wet. Water your plant thoroughly until water runs from the bottom of the pot, then allow the top 2 inches of soil to dry between waterings. Feel the soil with your finger to judge its dryness. In time you’ll probably start to develop a routine for when to water as you become familiar with the peperomia plant’s specific water needs.
Avoid over-watering your peperomia as this can lead to root rot and the demise of your plant. If you’re concerned about over-watering, be sure to grow your plant in a clay pot. Clay is porous and allows some water to evaporate through the pot.

Best Temperature for Peperomia Plants

Peperomias grow best in temperatures between 60° to 80°F (16° to 27°C). Be sure to keep your peperomia plant away from drafty locations such as near an exterior doorway or near forced air vents that might expose your plant to extremes of heat and cold.

Soil for Peperomia Houseplants

It’s important to grow your peperomia in a soil mix that provides good drainage. Usually, an all-purpose potting mix for houseplants is sufficient, but if your soil seems dense, add some perlite or orchid bark to help loosen the soil and create space for water to move more freely. A good ratio to start with is one part perlite to three parts soil.

Feeding Peperomia Plants

Fertilize your peperomia once a month when the plant is actively growing; usually in spring and summer when days are longer. Give it a rest in the winter when light is lower and plant growth is slower. You can use a general-purpose liquid feed for houseplants or apply a slow-release, granular feed in early spring to release a little bit of fertilizer when you water.

Propagating Peperomia Plants

Peperomia plants are incredibly easy to propagate from stem or leaf cuttings. Stem cuttings can be started in soil or water. Here are tips for different ways you can propagate peperomia plants:

Starting Peperomia Cuttings in Soil

  • Look for a healthy stem and cut it long enough to insert in a small pot of fresh, sterile potting soil. If possible, take several cuttings from your peperomia plant to increase your chances of success.
  • Dipping the cut end of the peperomia stem in rooting powder can help speed up the process but it will still take a few weeks for roots to start developing.
  • Place the potted peperomia cutting in a location that receives bright, indirect sunlight. Keep the soil moist, but not soggy wet. Your peperomia cutting will be busy growing roots for a while, but be patient and you will eventually see leaves emerge from the base of the cutting. It can take two months or longer for new leaves to appear.
  • You can also propagate peperomia plants from a single leaf. Snip off a leaf with just a small bit of stem. Set the end of the leaf with the stem into the soil until it is just buried. As with a stem cutting, place the potted leaf cutting near a bright window and keep the soil moist. Roots and leaves will emerge directly from the leaf.

Starting Peperomia Plants in Water

  • Perhaps the easiest way to propagate a peperomia plant is in a glass of water. Just like for soil propagation, you need to cut a stem long enough to reach the water. Remove any lower leaves that will be submerged in the water. Submerged leaves might rot and cause problems later. Place the cuttings near a bright window.
  • Pour off the water weekly and replace it with fresh water. The fun of propagating peperomia plants in water is that you can easily see and check the root development. Once the cuttings have grown roots about a half-inch long, they can be potted in soil. Continue to keep the soil moist, but not soggy, until leaves start to emerge.
  • No matter which propagation method you choose, once a small plant has developed you can adjust to a watering schedule that is more suited to a mature potted plant.

More Options for Expanding Your Houseplant Collection

Another group of tried-and-true houseplants that come in an array of shapes and sizes is philodendrons. Just like peperomia plants, it’s quite possible that a philodendron would have been found growing on your great-grandma’s windowsill. Learn all about philodendrons and decide which species you’ll want to add to your houseplant collection.
