Prayer plant folds its leaves upward every night — a normal circadian movement, not stress. It needs consistently moist soil, high humidity, and filtered or rain water (tap water minerals cause brown leaf edges). Non-toxic to pets, tolerant of lower light than most patterned plants, and typically costs $10-$25.
Key facts
- Native to Brazilian rainforest floor, growing as a low, spreading plant in shade and humidity.
- Folds its leaves upward each night in a circadian rhythm called nyctinasty — the movement is normal and driven by a small joint (pulvinus) at the base of each leaf.
- Sensitive to fluoride and mineral salts in tap water, which cause brown leaf edges over time — filtered or rain water prevents this.
- Non-toxic to cats and dogs, and tolerates lower light than most boldly patterned houseplants.
Care requirements#
| Plant type | Indoor only in most climates |
| Growing medium | Soil, moisture-retentive but well-draining potting mix |
| Light needs | Medium to bright indirect light; tolerates lower light better than most patterned plants |
| Water frequency | Every 5-7 days; keep soil consistently moist, never fully dry |
| Humidity | 50-60%+ preferred; brown edges appear in chronically dry air |
| Temperature range | 18-27°C (65-80°F); avoid below 15°C (60°F) |
| Fertilizer | Balanced liquid feed, half strength, monthly through spring-summer |
| Soil pH | 5.5-6.0 (acidic) |
| Drainage needs | Moderate — likes moisture but not standing water |
| Pot recommendation | Shallow, wide pot suits its low, spreading habit |
| Hardiness zone (outdoor) | USDA 11-12 (rarely grown outdoors) |
| Toxicity | Non-toxic to cats, dogs, and humans |
Growth & propagation#
| Mature size | 30cm tall, spreading to 45cm wide |
| Growth rate | Moderate |
| Propagation methods | Division at repotting, or stem cuttings with a node in water |
| Propagation difficulty | Beginner-friendly — divisions establish quickly, cuttings root in 3-4 weeks |
| Repotting schedule | Every 1-2 years in spring |
| Pruning needs | Trim leggy stems to keep the plant compact and encourage fresh growth |
Common problems & troubleshooting#
| Symptom | Likely cause | Fix |
|---|---|---|
| Brown, crispy leaf edges | Tap water minerals (fluoride, salts) or low humidity | Switch to filtered, distilled, or rain water; raise humidity |
| Leaves not folding at night anymore | Severe stress, usually from underwatering or root problems | Check soil moisture and root health; restore consistent care |
| Faded, washed-out leaf pattern | Too much direct light | Move out of direct sun to bright indirect light |
| Curling leaves | Underwatering or low humidity | Water thoroughly and raise ambient humidity |

Seasonal care#
Varieties & cultivars#
| Variety | Distinguishing trait | Note |
|---|---|---|
| 'Kerchoveana' (rabbit's foot) | Green leaves with dark blotches between veins | Classic, most common form |
| 'Erythroneura' (red prayer plant) | Bold red veins over dark green leaves | Most colorful and popular variant |
| 'Kim' | Cream-splashed variegation with purple spots | Less common collector form |
Buying checklist#
- Leaves are patterned crisply, not faded or washed out
- Edges are clean, without chronic brown crisping
- Soil is moist at time of purchase
- Watch the plant fold at night in the first days home — active folding indicates good health

Often confused with#
Name confusion warning#
"Prayer plant" is used loosely for several related plants. True prayer plant is Maranta leuconeura, but calatheas and ctenanthes — which also fold their leaves at night — are often sold under the same common name despite having different (usually fussier) care needs. Check the botanical name if care specifics matter to you.
Where it's actually grown#
Prayer plants are propagated by division and tissue culture in commercial greenhouses concentrated in Florida and the Netherlands, with red-veined cultivars dominating retail because their bolder pattern sells better than the subtler classic forms.
Import & biosecurity restrictions#
| Region | Note |
|---|---|
| Australia | Live plant imports restricted under biosecurity law; widely available domestically. |
| US | Domestic sale unrestricted; grown as a houseplant everywhere. |
| UK | No specific restriction; grown strictly as a houseplant. |
| India | No restriction; benefits from naturally humid regions of India. |
| Canada | CFIA permits required for commercial imports; grown as a houseplant. |

Frequently asked questions
Why does my prayer plant fold its leaves at night?
This is nyctinasty, a normal circadian movement driven by a water-pumping joint at each leaf base — it's a sign of health, not stress.
How much does a prayer plant cost?
A standard 4-6 inch potted plant typically runs $10-$25 in the US.
Is prayer plant pet-safe?
Yes, it's non-toxic to cats and dogs.
Why are my prayer plant's leaf edges turning brown?
Usually minerals in tap water or low humidity — switch to filtered or rain water and raise humidity.
Is prayer plant the same as calathea?
No — they're close relatives in the same family and both fold their leaves at night, but true prayer plant (Maranta) stays lower and spreads wider, and is generally more forgiving than calathea.
