Calathea Orbifolia is prized for its stunning, large round leaves with silver-green striping. It's one of the most beautiful foliage plants available but also one of the more demanding โ it requires consistent humidity and watering. Part of the "prayer plant" family, its leaves fold upward at night.
Care Guide
Light
Medium indirect light. No direct sun โ even brief exposure causes leaf burn and fading. North or east-facing windows are ideal. Too little light causes leggy growth.
Water
Keep soil consistently moist but never soggy. Water with filtered or distilled water โ calatheas are extremely sensitive to minerals and chlorine in tap water. Typically every 5โ7 days. Never let soil dry out completely.
Humidity
60โ80% required. This is the main challenge. Use a humidifier or group with other humidity-loving plants. Brown, crispy edges are the telltale sign of insufficient humidity.
Temperature
65โ80ยฐF (18โ27ยฐC). Highly sensitive to cold drafts and temperature swings. Keep above 60ยฐF at all times.
Soil
Peat-based mix with perlite for drainage. Slightly acidic (pH 6.0โ6.5). Must retain some moisture but not become waterlogged.
Fertilizer
Diluted balanced fertilizer monthly during growing season. Very sensitive to over-fertilizing โ use at half strength.
โ ๏ธ Toxicity
Non-toxic to cats and dogs. One of the best pet-safe statement plants.
โ๏ธ Propagation
Division only during repotting in spring. Cannot be propagated from leaf or stem cuttings.
Common Problems
Crispy brown edges โ low humidity (the #1 issue)
Curling leaves โ underwatering or low humidity
Yellowing leaves โ overwatering or cold temperatures
Fading patterns โ too much sunlight
Drooping at night โ normal! Prayer plants fold their leaves at night (nyctinasty)
Calatheas are called "prayer plants" because their leaves rise and fold together at night like hands in prayer โ a phenomenon called nyctinasty. They use specialized pulvini (motor cells) at the base of each leaf to follow their circadian rhythm.
