Read in: 5 min
Peperomia , also known as a baby rubber plant or radiator plant, is a pet safe houseplant that can be potted like the popular Obtusifolia, or used in a hanging basket like the rare String of Turtles. With more than 1,400 species of Peperomia plants and unique variegation (patterns and colors) on their foliage, you’d think caring for them would be hard. Luckily it isn’t.
This is a perfect houseplant for beginners and one that is always a showstopper in a collection as the plants can fenestrate and come with unique variegations like the popular Watermelon species. Whether yours has started to wilt, or you want it to grow faster, here’s how to care for your Peperomia plant.
We start with information about where Peperomia comes from naturally so you can learn about the environment it thrives, then the classifications so you can find similar houseplants if you want to grow your collection, then the instructions to keep a healthy plant happy and fix any health issues yours is facing.

Where Peperomia Originates
Peperomia originally came from Central and South America in both tropical and subtropical regions. Its popularity because of the unique variegation created a demand so people began buying Peperomia plants and they made their way across the world and can now be found growing in other tropical and subtropical regions of Africa and Asia.
The name is a combination of two Greek words "peperi" which means pepper and "homoios" which means similar or same as, which is a result of this plant looking very similar to the black pepper plant. Much like Hoya , Peperomia are epiphytes which means they grow by climbing up trees like an Ivy, but they do not harm or damage the tree by taking its nutrients and instead use it to get sunlight.
You can find Peperomia in the wild underneath the forest canopy and climbing trees which has led them to not be able to handle direct sunlight, they instead prefer the ambient light like they get in natural environments. They do love moisture and a bit of acidity from the rainforest's soils, but they cannot handle overwatering as a rainforest naturally drains excess water away.
Now that you know about the Peperomia plant’s natural environment, let's look at its classifications and then how to water it, treat diseases, make sure it gets the right type of sunlight, and more.

Peperomia Plant Care Instructions
Peperomia are the perfect houseplants for beginners that want a tropical flare without having to worry about consistent monitoring. They’re not set it and forget it like Sanevieria (Snake Plants) , but they’re still easy to maintain.
Watering
Water your Peperomia plant every 1 to 2 weeks once the top 1 or 2 inches of potting mix are dry. You can check the dryness by using your finger, a visual inspection, or a water meter.
Sunlight
Peperomia need between 3 and 6 hours of indirect sunlight each day, meaning you don’t want them to be directly in the sunbeams, but in a room with sunlight. This helps to mimic their natural environment in the tropical and subtropical rainforests.
Humidity and Temperature
This houseplant can thrive in ranges between 40% and 70%, which is most homes. Having a humidifier in the room or by the plants will be a good thing, or grouping your Peperomia with other plants so the plants create their own humidity levels.
Potting Mix and Nutrition
Peperomia need moisture retaining and aerating potting mix with a moderate level of acidity, so look for ingredients like coco choir, perlite or vermiculite, and orchid bark. Our Coco Bag is a perfect option for Peperomia.
Health Issues to Look For
Although this is a strong and durable houseplant, there are still health issues to watch for.
Discoloration and Fading
If the plant begins to fade in color, try moving it to a space with more sunlight like a south facing window as the sun crosses south in the USA. Yellowing and browning can be a result of overwatering or too much sunlight.
If you find yellowing and browning, here is how to fix and treat this.
Check to make sure the potting mix is not too wet. If it is change the potting mix and use a fungicide to kill any bacteria and fungus.
If the potting is not the problem, try moving the Peperomia plant further away from windows as this could be a condition called leaf burn. It’s similar to how our skin gets burnt by the sun.
You’ll also want to trim any brown and crunchy parts off of the leaves with sharp and clean shears.
Root Rot
Root rot will cause wilting, browning and yellowing of the leaves, and eventually kill the plant as the roots are literally rotting so the Peperomia cannot get water or nutrition. To find root rot carefully dig up the plant and look for brown or yellowish, mushy roots.
If your Peperomia has root rot, rinse the root system off with clean water and cut off any rotting roots. Next dump the potting mix out of the pot and clean the pot with a fungicide. Now replace the potting mix and replant your Peperomia plant, then monitor its health.
The Types of Peperomia Plants
With more than 1,400 species of Peperomia, there’s never going to be a shortage of options to add to your collection. That can also make it hard to decide which one or ones to buy. If you’re stuck choosing between the popular Obtusifolia or Watermelon, or you want a rare option, here are some staff favorites.
Peperomia 'Hope'
A soft trailing variety with round, succulent-like leaves that grow along thin, flexible stems. It’s ideal for hanging planters or shelves where it can gently spill over the edge, and it thrives in bright, indirect light with minimal fuss.
Peperomia obtusifolia
Also known as the baby rubber plant, this variety has thick, upright leaves and a tidy, low-growing shape. It comes in solid green and variegated forms and is perfect for desks, windowsills, or anywhere that could use a compact, easy-care plant.
Peperomia 'Watermelon'
Named for its silver and green striped leaves that resemble the rind of a watermelon, this variety grows in a low rosette and loves bright, filtered light. It’s a standout in any small-space plant collection and adds a splash of patterned foliage without taking up much room.
Peperomia 'Ripple'
This cultivar features heavily textured leaves with ruffled edges and deep veining. It comes in a range of colors from deep green to rich burgundy and offers big visual impact in a small footprint—great for mixed plant displays.
Peperomia 'Raindrop'
With its large, glossy, teardrop-shaped leaves, Raindrop has a sculptural quality that looks great solo or as part of a grouping. Its upright growth habit and thick leaves make it slightly more drought-tolerant than thinner-leafed varieties.
