Prayer Plant
Maranta leuconeura · Herringbone Plant
It grows low across the shaded floor of Brazilian rainforests, in consistent moisture and deep shade. Every night its hand-painted leaves rise and fold shut like praying hands, then flatten again at dawn.

Where it's from
Brazil
Brazilian forest floor
Native to tropical rainforest, the Atlantic Forest and Amazon margins, in deep shade and consistent moisture.
Outdoors: zones 11–12
True tropical. Frost kills it, so everywhere cooler it lives indoors.
Under-counted in the wild
Its Atlantic Forest home is among the most deforested biomes on Earth, and new Maranta species are still being found.
It moves every night
At dusk the prayer plant raises and folds its leaves shut like praying hands, a movement called nyctinasty, then flattens them at dawn. It is driven by water pumped in and out of a hinge-like swelling, the pulvinus, at the base of each leaf.
A 24-hour rhythm
The folding follows a daily light cycle, opening by day and closing at night.
Hand-painted leaves
The herringbone form carries bright red veins over dark green; the rabbit-tracks form shows twin brown blotches.
Grown for foliage
Its small white flowers rarely appear indoors and are insignificant; the leaf is the whole point.
How to keep it
LightBright, indirect
Dappled shade; north-facing windows are ideal. Direct sun bleaches the colours and scorches the leaves.
WaterKeep evenly moist
Consistently moist in growth, never soggy. Sensitive to fluoride, chlorine and salts; many use filtered or rainwater.
HumidityHighA rainforest-floor plant; dry air gives it brown, crispy edges. A pebble tray or humid room helps.
Temperature15–24°CKeep it above about 16°C, no cold drafts. Frost-intolerant.
SoilRich, peat-based mixWell-draining, but still holds moisture.
FeedingLight, in growing seasonA diluted balanced feed monthly during active growth. Over-feeding burns the leaf tips.
DifficultyEasy to moderateForgiving overall, but it browns at the first sign of dry air or hard water.
With petsNon-toxicListed safe for cats, dogs and horses by the ASPCA. A genuinely pet-safe foliage plant.
PropagationDivisionSplit the clump at repotting, each piece with roots and leaves. Stem-tip cuttings also root at a node.
RepottingEvery 1–2 yearsIn spring, or when root-bound. A good time to divide.
What the data says
What it costs
A box-store staple. The common forms are cheap and mass-produced.
$8–30
Uncommon sports and named cultivars like 'Lemon Lime' run a little higher, roughly $20 to $60. No four-figure mania.
The clean-air myth
Prayer plants get swept into NASA air-purifying listicles, on the back of a sealed-chamber study.
10–1,000
plants per square metre would be needed to match a room's ventilation (Cummings and Waring, 2019). The 1989 test used sealed boxes with no airflow. Keep it for the nightly leaf-folding.
IUCN · Not assessed
In the wild
One of the most cultivated foliage plants on Earth, yet never given a global threat status.
Its Brazilian Atlantic Forest home is among the most deforested biomes on Earth, and new Maranta species are still being described from the Amazon. Much of its wild diversity is under-documented even as the forest is cleared. Thriving in our homes, under-counted in the wild.
When it sulks
Brown, crispy tipsThe number one complaint: low humidity, or fluoride, chlorine and salt in tap water. Over-feeding also burns tips.
Faded, bleached leavesToo much direct sun, which washes out the pattern.
Yellowing, mushy baseOverwatering and root rot. It needs moist but well-drained soil.
Leaves not foldingA disrupted light cycle, thirst, or stress.
Spider mitesThey love the dry air that stresses it. Raise humidity and treat early.
