Ripple Peperomia

Peperomia caperata

Deep-ridged, crinkled hearts on rosy pink stalks, in a tidy little tuft. Stays small and asks for very little.

: Dim to filtered

Loves sheer-curtain sun; can sit in a dim spot for months

Happiest near a bright window or behind a sheer curtain, and it gets by for long stretches in a darker spot. Light coming from the side shows off its ridges best.

A few feet back from an east window can work well, or right at a south or west one with sheer fabric drawn. In a north-facing room, keep it close to the glass.

At 6-8 inches it fits on a desk, and NC State notes it performs well under bright fluorescent lights, which makes it a common desktop plant even far from a window.

The light NC State lists for it includes dappled sun, the kind that comes down through a canopy of leaves all day. Sheer fabric over a window is the closest indoor copy.

Soft, broken light is what a forest-floor plant like this one grew up under. Give it that when you can, and it copes when you can’t.

: 2-3× a month

Dry between drinks, not bone-dry; no wet soil or drafts

About every 7-10 days in summer, 2-3 weeks in winter, with the soil drying in between. It won’t tolerate soggy soil, which invites root rot, and it minds cold drafts; long bone-dry stretches wear on it too.

Pour at the soil line and keep the leaves dry. NC State ties wet foliage to leaf spot, and the deep furrows on this one can hold droplets.

It’s fine in medium to low humidity (NC State), though a heated winter can run drier than that. If your home gets very dry, a humidifier nearby may help (Clemson, NC State).

If the ruffled leaves start to curl or yellow, NC State reads that as overwatering. Give the next drink a few extra days.

Gone for a while? Two weeks is fine if it’s watered the day you leave; set it back from a sunny window so the soil dries more slowly.

: Small

Crinkled, ruffled hearts in a slow tuft up to 8 inches

A tight mound 6-8 inches tall that grows slowly and rarely needs repotting, so the pot it comes in may last for years. Set it on a desk by your keyboard, where you’ll see every ridge.

Each leaf is only about 1½ inches long, but it rides on a pink to red stalk twice that length (NC State), so the mound is really a crowd of tiny hearts held up on stilts. In a pot it tends to spread about as wide as it is tall, roughly 6-10 inches across (MoBot, Clemson).

Those long stalks make it easy to share: in spring, a leaf snipped with its stalk attached can root into a fresh tuft (NC State recommends leaf or stem tip cuttings).

: Pet & kid safe

Nothing to worry about for dogs, cats, or kids

DogsSafe

The ASPCA lists it as non-toxic to dogs and cats, and the Children’s Hospital of Philadelphia and UConn list peperomias as nontoxic for kids. Nothing to worry about in a home with all three.

Good news all around. The ASPCA records its toxic principle as simply non-toxic, under a whole string of its names: emerald ripple, green ripple, little fantasy, metallic peperomia, and silver heart. UC ANR includes it on a short list of the best pet-⁠safe houseplants.

The one caveat is the ASPCA’s general one: eating a lot of any greenery may bring on vomiting or a sour stomach in a dog or cat, messy but not dangerous. Call your vet if it keeps up.

For a home with a crawler or a cat, it’s an easy choice. If yours treats the ridged leaves like a chew toy, the plant is the one at risk, and a higher shelf saves its looks.

ASPCA: safe for dogs.

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 60°F. Keep it away from cold glass in winter. Humidity can drop to 15% without trouble.

Temperature: 65-86°F

: Mealybugs

Mealybugs, mites, whiteflies: check leaf undersides

Mealybugs hide in the leaf axils, spider mites in the ridges underneath, and whiteflies on the undersides. Fungus gnats, scale on the stalks, and aphids on new growth turn up too.

Aphids

Not many. Mealybugs and spider mites turn up now and then, but root rot from wet soil is the one that matters.

Mealybugs look like tufts of white cotton tucked into the leaf joints and the folds of the ripples. Wipe them out with a cotton swab dipped in rubbing alcohol, then check again next week.

Spider mites leave fine webbing and a dusty, speckled look. Rinse the plant in the shower, undersides of the leaves included, and let it dry off before it goes back. Tiny black flies around the pot are fungus gnats, a sign the soil stays too wet: let it dry out more between soaks and they fade away.

Brown or black spots on the leaves are leaf spot, a fungus that likes wet leaves: pinch off the spotted ones and keep water off the rest. Stems going soft and black at the soil mean root rot (see Troubleshooting).

Feed monthly spring to fall; pinch once a year

Feed monthly from spring to fall, never in winter. Pinch above a node once in spring or summer so it branches, trim old leaves twice a year, and repot in spring every few years.

Feed6× a year
Deadhead2× a year
Prune2× a year
Pinch1× a year

A small pot with a drainage hole and a mix that drains fast; a houseplant or cactus mix works. Its roots are small, and a big pot of wet soil rots them.

It doesn’t need a new pot every year. Repot every few years, into a pot just one size up.

Food is optional: a weak liquid fertilizer now and then in spring and summer, and none in fall and winter.

: Suave

Deeply ridged green hearts on rosy stalks, in a tidy tuft

Each green heart is crinkled into deep ridges, with a waxy, glossy surface, and the stalks run rosy pink. The leaves pack into a tidy tuft that covers the soil completely.

Fun fact

Caperata is Latin for "wrinkled," and the ridges run so deep the creases look nearly black. Named forms come red underneath ('Rosso'), purplish red ('Red Ripple') or silvery green ('Frost').

Designer tips

Small, crinkled, and a little retro, it suits a desk, a nightstand, or a bathroom sill.

Troubleshooting

It’s dropping leaves

Too much water, most often. Letting the soil dry between soaks, every 7-10 days in summer and 2-3 weeks in winter, usually settles it; a cold draft from winter glass or an outside door can do it too.

Stems are going soft and black at the base

Root rot, from soil that stayed wet. Once most stems have gone it rarely recovers, so a few healthy leaves, cut with an inch of stalk and pushed into damp mix, give you a fresh start; a smaller pot and less water help next time.

Brown or black spots on the leaves

Leaf spot, a fungus that likes wet leaves, and the deep ridges hold droplets. Pinch off the spotted leaves if they bother you, and pour at the soil line from now on.

Is it safe for my cat or dog?

Yes. The ASPCA lists it as non-toxic to dogs and cats, and CHOP lists peperomias as nonpoisonous for kids. Eating any plant can upset a pet’s stomach, but this one isn’t poisonous.

Thin white spikes are sticking up

Its flowers, which look a bit like mouse tails and come in summer and fall. They do the plant no harm; leave them or snip them off at the base.

Can it live without a window?

For a stretch: NC State says it gets by in low light for months and does well under bright overhead lights. For the long run, a few feet from an east window suits it best.

Does it need a bigger pot?

Rarely. It’s happy in the same small pot for years, and a big pot holds more wet soil than its small roots can use, so go one size up only once roots fill the pot.

Can it go outside for the summer?

Yes, in shade, once nights stay above 60°F, which in Chicago usually means June. Keep it out of heavy rain and where sun doesn’t land on the leaves, and bring it back in before nights cool in early fall.

Propagation

Easily, from a single leaf.

Cut a healthy leaf with an inch of its stalk, push the stalk into a small pot of damp mix, and keep it where sun doesn’t land on the leaves; a clear plastic bag over the top keeps it humid.
New plants form at the base of the stalk.
Growers root cuttings and finish a small pot in 3-5 weeks; at home, expect it to take longer.

A stem tip works too: cut a piece with a few leaves, strip the lowest ones, and root it the same way or in a glass of water, then pot it up once roots and new leaves form.
