Peperomia Varieties — 12 Worth Growing, in 3 Care Groups

Peperomia varieties number over 1,500 species, but 12 cover the houseplant trade. Which group yours is in decides the watering, and that is the whole job.

The genus runs to more than 1,500 species, which sounds unmanageable and is not. A dozen varieties cover almost everything sold, and they sort into three groups by leaf — which is the only thing you need in order to water them correctly.

The short answer

Peperomia varieties fall into three care groups by leaf type. Thick succulent-leaved kinds such as obtusifolia, raindrop and ruby glow store water and want the compost dry through between waterings. Rippled and textured kinds such as caperata and watermelon peperomia have thinner leaves, want slightly more frequent water and resent dry air. Trailing kinds such as string of turtles and trailing jade are the smallest-rooted and the quickest to rot. All of them are semi-epiphytic with fine shallow roots, so they want small pots and a chunky open mix, and the whole genus is listed non-toxic to cats and dogs.

Three groups by leaf: succulent, rippled, trailing
Thicker leaf = longer between waterings
Small pots, chunky mix — the roots are fine and shallow
Non-toxic to cats and dogs across the genus
Dropping leaves is overwatering or cold, nearly every time

The three care groups

What the leaf tells you about the watering

Group	Leaf	Light	Water	Humidity
Succulent-leaved	Thick, firm, glossy	Bright indirect to some sun	Dry through, then soak	Indifferent
Rippled / textured	Thinner, corrugated	Bright indirect, no sun	When top third dries	Prefers 50%+
Trailing	Small, beaded	Bright indirect	Sparingly; rots fastest	Moderate

Succulent-leaved varieties

1. Peperomia obtusifolia — baby rubber plant. The toughest in the genus and the one to start with. Thick spoon-shaped leaves, upright to about ten inches, available plain green or variegated. Forgives a missed fortnight.

2. Peperomia polybotrya — raindrop. Large glossy teardrop leaves on upright stems, often mistaken for a pilea. Same care as obtusifolia, slightly more inclined to get leggy in low light.

3. Peperomia graveolens — ruby glow. Boat-shaped leaves, green on top and deep red underneath, genuinely succulent. The most sun-tolerant of the group and the one that most resents a damp winter.

4. Peperomia ferreyrae — happy bean. Narrow folded leaves like green beans. Looks nothing like the rest of the genus and is treated as a succulent in practice.

5. Peperomia clusiifolia — red-edge, ‘Ginny’, ‘Rainbow’. Thick leaves edged cream and pink. Needs good light to hold the colouring; reverts to green in a dim corner.

Rippled and textured varieties

6. Peperomia argyreia — watermelon peperomia. The famous one: silver and green banded leaves on red stems. Thinner-leaved than it looks, so it wants more regular water than obtusifolia and suffers in dry heated air.

7. Peperomia caperata — emerald ripple. Deeply corrugated heart-shaped leaves, in green, ‘Rosso’ red, or near-black ‘Schumi Red’. Compact, and the group most prone to rot at the crown if water sits in the centre.

8. Peperomia griseoargentea — ivy-leaf peperomia. Silvery, quilted, with sunken veins. Slow and handsome; the same care as caperata.

9. Peperomia metallica var. colombiana. Dark bronze leaves with a metallic sheen and a pale central stripe. Wants the humidity of the group and the brightest light it can get without sun.

Trailing varieties

10. Peperomia prostrata — string of turtles. Tiny round leaves patterned like a shell, on fine trailing stems. Beautiful, and the least forgiving plant in the genus: fine roots, a shallow pot, and no tolerance for sitting wet.

11. Peperomia rotundifolia — trailing jade. Round pea-like leaves on thread stems. Easier than string of turtles and does well in a hanging pot.

12. Peperomia puteolata — parallel peperomia. Pointed leaves with cream parallel veins on red stems, semi-trailing. A good middle choice between the upright and the fully trailing kinds.

Watch out

The commonest way to kill any of these is a pot that is too big. Peperomias are semi-epiphytes — in the wild they grow in leaf litter and moss on tree bases, not in soil — so a deep pot of ordinary compost holds a reservoir of water the fine roots never reach and never dries. Pot up one size only, and use a mix with bark or perlite at a third by volume.

Care that applies to all twelve

Light. Bright indirect. The succulent-leaved kinds take an hour or two of direct morning sun; the rippled ones scorch in it.
Water. By weight, not by schedule. Lift the pot — light means water, any heft means wait.
Temperature. Above 55°F. They are tropical understorey plants and cold does visible damage fast.
Feeding. Half-strength balanced feed monthly in spring and summer only.
Propagation. Leaf cuttings work across the genus, which is unusual and makes a damaged plant recoverable from a single leaf.

Common questions

How many peperomia varieties are there?

The genus holds over 1,500 described species, which makes it one of the largest in the plant kingdom. Perhaps fifteen to twenty are in general houseplant cultivation, and a dozen account for almost everything sold. The number that matters for care is three, because the varieties fall into three groups by leaf type and each wants a different watering interval.

Are peperomias toxic to cats and dogs?

No. The ASPCA lists peperomia as non-toxic to both cats and dogs, which is unusual among glossy-leaved houseplants and is one of the main reasons the genus is recommended for homes with animals. That applies across the genus rather than to particular varieties.

Why are my peperomia leaves dropping?

Almost always overwatering, and almost always in winter. Peperomias store water in their leaves and have fine, shallow roots adapted to growing in leaf litter rather than soil, so saturated compost kills the roots within days and the leaves fall soon after. The second cause is cold — below about 50°F they drop leaves even when the watering is right.

Which peperomia is easiest to grow?

Peperomia obtusifolia, the baby rubber plant. Thick succulent leaves mean it tolerates a missed watering better than any of the rippled types, it is unfussy about light short of direct sun, and it propagates from a leaf. Watermelon peperomia is the most popular but is noticeably less forgiving of both dry air and overwatering.

Do peperomias need big pots?

No — they do better in pots that look too small. The root system is fine and shallow and the plant is semi-epiphytic, so a large volume of compost holds water the roots never reach and stays wet long enough to rot them. Pot up one size at most, and only when roots show at the drainage holes.
