Overview
Calathea orbifolia is grown for its leaves alone. Each one is broad and almost round, washed in silvery green and striped like fine ribbon, and at dusk the whole plant lifts its foliage and folds it together, the trait that earns the prayer plant name. It comes from the rainforest floor of eastern Brazil, and that origin tells you most of what it wants from you.
It belongs to the prayer plant family, the Marantaceae, and now carries the accepted botanical name Goeppertia orbifolia after a reshuffle of the old Calathea genus. The label changed but the plant didn't, and most growers and shops still call it by the familiar Calathea name.
This is a demanding plant, no way around it. It drinks clean water, lives in humid air, and sulks the moment either one slips. Get the light, water, and humidity right, though, and it rewards you with fast, lush growth and some of the most striking leaves you can keep indoors.
Care
The short version: bright indirect light, never direct sun, watered with distilled water or rainwater to keep the soil evenly moist, in warm rooms at 65°F to 75°F (18°C to 24°C) and humidity of at least 60%.
Light
Give it bright, indirect light and keep it out of direct sun, which bleaches the markings and scorches the leaves. It also gets by in partial shade, though growth slows and the colors fade in a dim corner. Early-morning or well-diffused sun is the most it should take.
Water
Keep the soil evenly moist but never soggy, easing off through winter when growth slows. The water itself matters as much as the amount, so use distilled water or rainwater. The fluoride and salts in tap water are what burn the brown tips and edges onto the leaves.
Soil
Use a moist but well-drained mix, something loamy or peaty that holds water without turning to mud. A slightly acidic to neutral pH of 5.5 to 7.0 suits it. The aim is soil that stays damp between waterings yet still drains freely.
Temperature
Warm, steady room temperatures of 65°F to 75°F (18°C to 24°C) keep it happy. It has no tolerance for cold drafts or sudden chills, so keep it clear of doorways, vents, and frosty windows.
Humidity
This is the make-or-break factor. Aim for at least 60% humidity, well above what most homes offer, with a humidifier doing the heavy lifting. A pebble tray and grouping it with other plants help, and dry air is the fastest way to crisp tips and curling leaves.
Feeding
Through the growing season, spring into summer, feed monthly with a balanced houseplant fertilizer at the usual strength. Stop over winter while the plant rests. It isn't a heavy feeder, and too much fertilizer leaves salt that scorches the leaf edges.
Pruning
Pruning is barely a job here. Just remove damaged, browned, or yellowing leaves at the base as they appear, which keeps the plant tidy and pushes its energy into healthy growth.
Repotting
Repot every 1 to 2 years in spring, or sooner if roots circle the pot, water runs straight through, and growth stalls. Step up just one pot size into fresh mix, since this plant resents sitting in too much soil.
Size & spacing
Indoors it reaches 2 to 3 feet (61 to 91 cm) tall and spreads 12 to 24 inches (30 to 61 cm) wide. Give it elbow room so the big leaves can spread and air can move freely around them.
Troubleshooting
Almost every Calathea complaint shows up on the leaves, and almost every one traces back to water quality, humidity, or light. Read the leaves and they'll tell you what's wrong. Match what you see below, then fix the cause rather than just trimming the damage.
Wilting, yellow leaves and soft, dark roots
Soil that stays wet drowns the roots and brings on root rot, which turns them brown and mushy instead of firm and pale. Slide the plant out, cut away every rotted root, and repot into fresh, well-drained mix. From there, water only enough to keep it evenly moist and never let it sit soggy.
Fix:
- Remove plant and cut away rotted roots
- Repot into fresh well-drained mix
- Water only to keep evenly moist, never soggy
Washed-out markings and scorched patches
Too much light bleaches the bold pattern and burns pale patches into the leaves that catch the most sun. Direct afternoon sun is the usual culprit. Move the plant into bright indirect light or partial shade and the new growth comes back richly marked.
Fix:
- Move to bright indirect light or partial shade
- Avoid direct afternoon sun
Fine webbing and pinprick speckling on the leaves
Dry air invites spider mites, and they hide on the leaf undersides where you'll see faint webbing and a dusting of tiny moving dots. Rinse the foliage, then treat with insecticidal soap or horticultural oil and repeat until they're gone. Keeping the humidity high is the best way to stop them coming back.
Fix:
- Rinse foliage
- Treat with insecticidal soap or horticultural oil
- Raise humidity
Brown, crispy tips and edges on the leaves
This is almost always the tap water. Fluoride, chlorine, and dissolved salts build up and scorch the leaf margins while the centers stay green. Switch to distilled water or rainwater, raise the humidity to at least 60%, and trim the damaged edges if they bother you.
Fix:
- Switch to distilled water or rainwater
- Raise humidity to at least 60% with a humidifier or wet-pebble tray
- Trim damaged edges if desired
Leaves curling or rolling inward
Leaves roll inward when the air is too dry or the soil has gone thirsty, and the edges often brown along with it. Push the humidity up to at least 60% with a humidifier or pebble tray, and keep the soil consistently moist. The leaves usually relax once the plant is comfortable again.
Fix:
- Increase humidity to at least 60%
- Keep soil consistently moist
Brown or rusty spots dotting the leaves
Distinct spots that show up after watering point to water sitting on the foliage. Water at the soil instead of over the top, and skip the misting that leaves the leaves wet. A bit more air movement around the plant helps the surface dry faster.
Fix:
- Water at the soil level and avoid wetting leaves
- Improve air circulation
Toxicity
Good news for pet owners: this is one of the safest plants you can keep. The ASPCA lists Calathea and the prayer plant family as non-toxic to cats, dogs, and horses, and NC State Extension says the same for Goeppertia orbifolia by name. A nibble from a curious cat or dog won't poison them.
Safe for
People · Cats · Dogs · Horses · Rabbits · Livestock · Birds
Cats None
The ASPCA lists this plant as non-toxic to cats, so a curious nibble is nothing to worry about. A cat that gorges on any houseplant might bring it back up, but that's a full stomach, not poison.
Dogs None
Safe for dogs, with both the ASPCA and NC State Extension placing it on the non-toxic list. There's no need to fence it off or rush to the vet if your dog takes a bite.
Horses None
Horses can graze near it without any risk, since the ASPCA rates the prayer plant family non-toxic to horses.
Rabbits None
There's no toxin here to harm a rabbit. Even so, leafy houseplants aren't a real part of a rabbit's diet, so let it be a stray nibble rather than a meal.
Livestock None
Goats, sheep, and other livestock face no poisoning from this plant, which carries none of the toxins that make so many ornamentals a risk in the field.
Birds None
Pet birds are in no danger if they pick at a leaf. The plant holds nothing toxic, though it's worth keeping any fertilizer or leaf-shine residue off foliage a bird might reach.
People None
Handling and the odd accidental taste pose no poisoning risk to children or adults. It isn't grown to be eaten, but it sits firmly on the non-toxic list.
How to propagate
There's only one way to make more of this plant, and it's splitting the one you have. It won't root from a cutting, so division in spring is the route.
DivisionModerate
Spring · Several weeks to establish after potting up divisions
Division is the only way to multiply this plant, since it won't grow from a leaf or stem cutting. Do it in spring, when you can lift the rootball, tease it into clumps that each keep their own roots and leaves, and pot them up separately. Give the divisions a few weeks of warm, humid, evenly moist conditions and they settle in and start growing on their own.
Myths
Calathea orbifolia is the current correct botanical name.
That name is now a synonym. Kew's Plants of the World Online gives the accepted name as Goeppertia orbifolia, the result of a 2012 reshuffle that moved many Calathea species into the genus Goeppertia. The plant is the same; only the label on it has changed.
Prayer plants like this one are toxic to cats and dogs.
They aren't. The ASPCA lists Calathea and the wider prayer plant family as non-toxic to dogs and cats, and NC State Extension says the same for Goeppertia orbifolia by name. This is one of the safest plants you can keep around pets.
