Peperomia
Peperomia obtusifolia
Glossy, spoon-round leaves on pink-tinged stems, in a desk-sized mound. Thick leaves hold water, so a missed week barely shows.
Also called baby rubber plant and pepper face

: Dim to bright
Bright and out of the sun; it can coast in a dim spot
The plain green kinds take low light in stride for months; variegated ones want more. It does best set back from a bright window, out of its direct rays.
In the wild, from Florida to tropical South America, it sometimes grows perched on other plants as an epiphyte (Kew), up off the shaded forest floor (Clemson Extension).
An east window can work if it sits a little back from the pane. In a south- or west-facing room, a sheer curtain or the far side of the room keeps the rays off its glossy leaves.
The genus nickname, radiator plant, points to its love of warmth (NC State), and it dislikes drafty spots. Come winter, give it the warm side of the room rather than the cold window.
: 2-3× a month
Every 10-14 days in summer; wet soil is its downfall
About every 10-14 days in summer and 2-3 weeks in winter, with the soil drying halfway down between. Leaves nearly as thick as a succulent’s carry it past a missed watering; constant wet won’t.
It adapts to the humidity of most homes and leans toward medium to low (NC State). If winter heat leaves a room very dry, a humidifier helps (Clemson; NC State).
When you pour, slip the spout under its cupped leaves; NC State advises against wetting them, to head off leaf spots.
Very dry soil sits on NC State’s list of its dislikes right beside wet soil, so the sweet spot is the middle: halfway dry, then a drink.
Gone for a while? Three weeks is fine if it’s watered the day you leave; its leaves are its water tanks.
: Small
A bushy mound that steadily fills to 8-12 inches
Thick, upright stems carry round, cupped leaves in a tidy mound that steadily fills out to 8-12 inches across. Sized for a desk, nightstand or bookshelf; a single leaf on its stalk can root and start another.
To start one from a stem instead, take a 4-6 inch cutting, strip its lower leaves and cut just below a leaf joint (Clemson Extension).
NC State describes its habit as both erect and rounded, and open and spreading. Because the mound grows about as wide as it is tall, it fills a small round footprint evenly: a side table, the center of a kitchen island. Set a row of them along a deep sill and the pink-tinged stems show under the glossy leaves.
: Pet & kid safe
Nothing to worry about for dogs, cats or kids
The ASPCA lists it as non-toxic to dogs and cats, and the Children’s Hospital of Philadelphia lists peperomia among plants that are nonpoisonous for kids.
Horses get the ASPCA’s all-clear too. For children, peperomia also appears on UConn’s list of nontoxic houseplants; both UConn and CHOP list it by genus (CHOP; UConn).
Eating plant material of any kind may still bring on vomiting or a mild upset stomach in pets, a fair caveat the ASPCA adds for every houseplant. That’s a general warning, not a mark against this plant.
That makes it a good pick for a home with a crawler or a chewer. If a pet treats it as a snack, move it up to a shelf, mostly to save its leaves.
Cats and dogs: The ASPCA lists it as non-toxic.
Kids: CHOP lists it as non-poisonous.
: Dry OK
65-86°F; dry air is fine
Happiest at 65-86°F, and it shouldn’t sit below 50°F. Humidity can drop to 15% without trouble.

- 65-86°F
: Mealybugs
Mealybugs, spider mites; check joints and leaf undersides
Mealybugs hide in the leaf axils and stem joints, and spider mites live on the leaf undersides, so flip a few leaves. Whiteflies (undersides), scale (stems) and fungus gnats (moist soil surface) can also visit.
- Mealybugs
- Spider mites
- Whiteflies
- Fungus gnats
- Scale
Not many. Rot from soggy soil is the real risk; fungus gnats and a few sap-sucking bugs turn up now and then.
Fungus gnats are the tiny flies that hover over damp soil. Letting the soil dry between soaks kills their larvae; if they hang on, water in a Bti product (the kind sold for mosquitoes), which kills the larvae in the soil.
Mealybugs look like tufts of white cotton where the leaves meet the stems. Wipe them off with a cotton swab dipped in rubbing alcohol; a fingernail lifts scale, the small brown bumps.
Spider mites leave a speckled, dusty look and, in a bad case, fine webbing: rinse the plant in the shower, undersides of the leaves included. Whiteflies look like tiny white moths that flutter up when you touch it. If either keeps coming back, spray insecticidal soap under the leaves.
Stem and root rot is the disease to watch: the stem goes black and mushy at the soil line. Let the pot dry out, save any healthy tops as cuttings (see Propagation) and water less often. Leaf spot, tan to black patches on the leaves, is a fungus too; keep water off the leaves and cut off the worst.
: Little
Wipe leaves 2× a year; feed once, snip flower spikes
Twice a year, wipe the dust off and trim old leaves. In spring and summer, snip the flower spikes twice and feed once. Prune above a node to make it branch, and repot only every several years.
- Feed1× a year
- Prune1× a year
- Deadhead2× a year
- Clean leaves2× a year
A small pot with a drainage hole and a mix that drains fast: houseplant mix with some perlite or bark stirred in, or a cactus mix.
It doesn’t need a new pot every year. Repot every few years, in spring, into a pot just one size up.
Food is optional: a weak liquid houseplant fertilizer now and then in spring and summer, and none in winter. Its fine roots burn easily, so less is more.
: Simple
Glossy, spoon-round green leaves in a full mound
Round, cupped leaves in one plain green, waxy and glossy, on pink-tinged stems. They pile into a mound full enough to hide the soil.
Where to find me
Not yet pilferableFun fact
Snip a stem or even one leaf, and a new baby rubber plant grows without its parent lifting a finger. NC State recommends cuttings, though the RHS lists seed too.
Designer tips
Small, glossy and tidy, it’s the plant for a desk, a nightstand or a side table, where you see the shine up close.
Troubleshooting
It’s dropping leaves
Usually too much water: if the soil has stayed wet, let it dry out and water less often. A stem gone black and mushy at the soil line is likely rot, and a healthy top cut 4-6 inches long can root as a backup; a cold draft can drop a few leaves too.
Why are the lower leaves turning yellow?
Most often overwatering, which NC State Extension calls the big problem with this plant, so give it longer between drinks. If that’s not it and it hasn’t been fed in a year or more, a weak dose of fertilizer in spring can help.
The leaves are wrinkled and droopy
It’s thirsty: the thick leaves hold its water, and they wrinkle as it runs low. A good soak usually plumps them back up within a few days; if the soil is wet and it still droops, the roots may be rotting instead.
See all 9
It’s getting leggy
It wants more light. A spot closer to a window, out of the sun’s reach, helps, and a long stem cut just above a leaf branches from there; the tops you cut off root easily.
My dog ate a few leaves
Nothing harmful: the ASPCA lists it as non-toxic to dogs and cats, and CHOP lists peperomia as nonpoisonous for kids. Eating any plant can upset a pet’s stomach, so a big nibble might bring some vomiting.
Thin, tail-like spikes are sticking up
Those are its flowers: tiny cream-colored ones packed along a spike that people liken to a rat’s tail. They come in spring and summer when it’s growing well; snip them off if you don’t like the look, since it carries on either way.
Is it a succulent?
Not quite, though it acts like one: the thick leaves store water, which is why it hates wet soil. Unlike a cactus, it wants to stay out of the sun’s direct rays.
Is it a small rubber plant?
No. Baby rubber plant is a nickname for its thick, glossy leaves; the real rubber plant is a fig that grows toward the ceiling, while this one stays desk-sized.
Can it go outside for the summer?
Yes, in full shade, like a porch or under a tree, while nights stay above 60°F and somewhere rain won’t keep the pot soaked. Bring it in as fall nights cool, and check it for bugs first.
Propagation
Yes, and easily, from a stem or even a single leaf.
- Cut a stem 4 to 6 inches long, just below a leaf, and pull off the lower leaves.
- Stand it in a glass of water or push it into damp mix.
- Growers have cuttings rooted and filling a small pot in 3-5 weeks; at home, give it a little longer.
Or take a single leaf with an inch of its stalk and push the stalk into damp mix. A new plant forms at its base.
