Calathea is the genus of tropical foliage plants that challenges the idea that flowers are the most beautiful thing a plant can produce. With leaves painted in stripes, medallions, feathered brushstrokes, and geometric patterns in shades of green, pink, purple, silver, and cream — calathea turns foliage itself into living art. Each species displays a unique pattern that looks hand-painted, as though a botanical illustrator painstakingly decorated every leaf. No two species are quite alike, and even individual leaves on the same plant show subtle variation, making every calathea specimen genuinely one of a kind.
But calathea's most extraordinary feature is not its patterns — it is its movement. Every evening as light fades, calathea leaves fold upward from their horizontal daytime position, pressing together vertically like hands held in prayer. At dawn, they slowly unfurl back to horizontal. This daily rhythm, called nyctinasty, is driven by changes in water pressure in specialized cells (pulvini) at the base of each leaf stalk. The movement is subtle enough that you won't see it happening in real time, but dramatic enough that a calathea photographed at 2pm and again at 10pm looks like two different plants. Time-lapse videos of calathea's nightly prayer are among the most mesmerizing plant content on the internet.
Calathea species are native to the tropical Americas — primarily Brazil, Colombia, Ecuador, Peru, and Central America, where they carpet the floor of dense rainforests beneath the canopy. The genus was first described by German botanist Georg Friedrich Wilhelm Meyer in 1818.
How to Plant Calathea in the Philippines
Soil, spacing, and the best planting approach for Philippine conditions.
Calathea is readily available at Philippine plant shops, weekend markets, and online sellers. Common species like C. ornata (pinstripe) and C. lancifolia (rattlesnake) are affordable at ₱150-500. Rarer varieties like orbifolia, White Fusion, and warscewiczii range from ₱500-2,000+ depending on size and supply. Unlike aroids, calathea cannot be propagated from stem or leaf cuttings — purchasing a plant or dividing an existing one are the only options.
Care Guide
Keep your Calathea healthy and thriving.
Low to medium indirect light — calathea is a true shade plant. It evolved beneath the dense canopy of tropical rainforests where only 2-5% of sunlight reaches the forest floor.
Consistent moisture is essential — calathea wants evenly moist soil that never fully dries out and never becomes waterlogged. Water when the top 2-3 cm of soil feels dry to the touch.
Moisture-retentive but well-draining: 2 parts coco peat + 1 part perlite + 1 part compost or fine orchid bark. The mix should hold moisture like a wrung-out sponge — damp but not dripping.
Humidity is calathea's most critical care factor — more important than light, water, or soil. Maintain 60-80% relative humidity around the plant.
Light feeder — calathea does not need heavy fertilization. Apply balanced liquid fertilizer (10-10-10 or 20-20-20) at quarter to half strength once a month during the growing season (March-October).
Calathea does not require structural pruning — there are no stems to shape or vines to train. The only pruning needed is removing dead, yellowed, or heavily browned leaves by cutting the leaf stalk at the soil line with ...

Best soil and medium choices for Calathea.
Soil (Moisture-Retentive Mix)
BestA moisture-retentive blend of coco peat, perlite, and compost is calathea's ideal medium. The mix holds consistent moisture while the perlite component prevents waterlogging. This mimics the humus-rich, constantly moist forest floor where calathea grows naturally. Use plastic or glazed pots rather than terracotta to preserve soil moisture — terracotta wicks water away from roots.
Water
Not RecommendedCalathea cannot be grown in water long-term. Unlike aroids with adaptable aerial root systems, calathea has fine, fibrous roots attached to rhizomes that are not suited to aquatic culture. The rhizomes rot in standing water. Water culture is not viable even for propagation — calathea can only be propagated by rhizome division, not water-rooted cuttings.
Semi-Hydro (LECA)
PossibleSome experienced growers succeed with calathea in LECA semi-hydroponics, but it requires careful management. The transition from soil to LECA is stressful, and calathea's sensitivity to water chemistry means the nutrient solution pH and mineral content must be monitored closely. Not recommended for beginners — soil culture is far more forgiving for calathea specifically.
Ornamental Uses
How to use Calathea in your garden and home.
Calathea's spectacular leaf patterns, compact growth habit, and shade tolerance make it one of the most versatile indoor ornamental plants. Where most dramatic houseplants demand bright light and prominent positioning, calathea thrives in the quieter, dimmer spaces of a home — filling roles that few other beautiful plants can serve.
- Low-light statement plant: Calathea brings pattern, color, and visual drama to north-facing rooms, interior hallways, and shaded corners where most ornamental plants would languish. A large calathea orbifolia or medallion on a plant stand transforms a dark corner into a design feature
- Tabletop and shelf display: Compact varieties (lancifolia, ornata, makoyana) at 30-60 cm tall are perfect for coffee tables, desks, bookshelves, and plant stands. The upright, clumping growth habit is self-contained and does not sprawl or trail
- Bathroom and kitchen accent: Calathea's love of humidity makes it ideal for naturally humid rooms — bathrooms with natural light and kitchens with ambient moisture are excellent calathea locations that also happen to be rooms where stylish plant options are limited
- Bedroom plant: As a non-toxic, shade-tolerant, air-purifying plant that literally goes to sleep at night (leaves folding up), calathea is an ideal bedroom companion. The absence of toxicity is particularly important in bedrooms where pets may have unsupervised access
- Office and workspace plant: Calathea tolerates fluorescent and LED office lighting and brings organic warmth to workspace environments. The compact habit fits desk corners and reception areas
- Shaded garden ground cover: In Philippine outdoor spaces with dense shade — beneath large trees, under covered patios, in north-facing garden beds — calathea forms lush, patterned ground cover that no flowering plant can match in deeply shaded conditions
- Tropical garden understory: Planted beneath palms, ferns, and large-leaved aroids, calathea provides the understory layer of an authentic tropical garden composition, adding pattern and texture at ground level
- Container arrangements: Mixed planters combining calathea with ferns, selaginella, and other moisture-loving shade plants create miniature tropical ecosystems for covered outdoor spaces
Safety & Environmental Benefits
Toxicity info and air quality benefits.
Humans: Calathea (Marantaceae family) is considered non-toxic. No calcium oxalate crystals, no significant alkaloids, no poisonous compounds. Handling and touching the plant is completely safe. As with any non-food plant, ingesting large quantities of leaves could cause mild gastrointestinal discomfort from plant fiber, but calathea presents no poisoning risk. Safe for homes with small children. Pets: The ASPCA lists calathea as non-toxic to dogs and cats .
Calathea contributes positively to indoor air quality through its broad leaf surface area and active transpiration. The large, flat leaves of species like orbifolia, roseopicta, and makoyana provide considerable photosynthetic surface area relative to the plant's footprint, producing oxygen during daylight hours and participating in gas exchange with indoor air.
Common Pests & Diseases
Spot issues early and keep your plant healthy.
Spider mites
Calathea's #1 pest enemy — tiny mites that cause stippled yellowing and fine webbing, especially on leaf undersides. Spider mites thrive in hot, dry conditions — making air-conditioned rooms particularly susceptible. Prevention: maintain humidity, regularly wipe leaf undersides with a damp cloth. Treatment: neem oil spray, insecticidal soap, or miticide for severe infestations. Check incoming plants carefully — spider mites often arrive on newly purchased plants.
Fungus gnats
Small dark flies that hover around the soil surface. The adults are harmless but annoying; the larvae feed on root hairs and organic matter in moist soil. Calathea's preference for consistently moist soil makes it more gnat-prone than drought-tolerant plants. Prevention: allow the top layer to dry slightly between waterings (without letting deeper soil dry). Treatment: yellow sticky traps for adults, neem oil soil drench or mosquito bits (BTI) for larvae.
Mealybugs
White, cottony insects found at leaf axils and where leaf stalks meet the soil line. Suck sap and excrete sticky honeydew. Remove with alcohol-dipped cotton swabs. Neem oil spray for heavier infestations. Inspect the base of leaf stalks during watering — mealybugs hide in the tight spaces between stems.
Root rot
Mushy, dark roots caused by waterlogged soil — usually from poor drainage, overly dense soil, or pots without drainage holes. Calathea wants moist soil but cannot tolerate standing water around its roots. Symptoms: yellowing leaves that wilt despite moist soil, mushy stem bases, foul smell from soil. Treatment: unpot, trim all rotted roots, repot in fresh mix with proper drainage.
Leaf spot diseases
Brown or black spots with yellow halos, caused by fungal or bacterial pathogens spread by water splashing on leaves. Prevention: water at soil level, not over the leaves. Improve air circulation. Remove infected leaves promptly. Treatment: copper-based fungicide spray for persistent fungal issues.
Crispy leaf edges (physiological)
While not a pest or disease, brown crispy leaf edges are calathea's most common issue in the Philippines and is caused by low humidity (especially AC rooms), tap water chemicals, or inconsistent watering. Address the environmental cause — increased humidity and filtered water resolve most cases.
Frequently Asked Questions
Quick answers about Calathea.
Why do calathea leaves move at night?
Calathea exhibits nyctinasty — circadian leaf movement. Specialized cells (pulvini) at each leaf base shift water pressure, folding leaves upward at dusk and opening them horizontally at dawn. This "prayer" movement conserves water, prevents rain pooling, and may discourage nighttime insects. The movement is triggered by light changes — keep calathea near a window or in a room with regular light/dark cycles for the strongest movement.
Why does my calathea have brown leaf edges?
Multiple causes: (1) Low humidity — #1 cause, especially in AC rooms below 60%. Fix with a humidifier or pebble tray. (2) Tap water chemicals — chlorine and fluoride cause brown tips. Use filtered or rainwater. (3) Soil drying out completely between waterings. (4) Direct sunlight burns. (5) Cold drafts. Existing brown edges are permanent — trim with scissors at an angle. Correct the cause and new growth will emerge clean.
Is calathea toxic to pets?
No — calathea is ASPCA-listed as non-toxic to dogs and cats. Unlike aroids (monstera, pothos, philodendron) that contain toxic calcium oxalate crystals, calathea (Marantaceae family) has no toxic compounds. This makes it one of the safest ornamental plants for pet households. Eating leaves may cause mild stomach upset from fiber, but no poisoning risk.
What is the difference between calathea and Goeppertia?
In 2012, most ornamental "Calathea" species were reclassified into genus Goeppertia based on DNA studies showing the old genus was not monophyletic. Your "Calathea orbifolia" is scientifically Goeppertia orbifolia. However, the plant trade universally continues using "Calathea." Both names refer to the same plants — Calathea for commerce, Goeppertia for taxonomy.
Why are calathea leaves curling?
Curling is a distress signal — the plant reduces leaf surface to conserve moisture. Causes: underwatering (soil dried out), low humidity (dry air), heat stress (near hot window or appliance), or root problems (rot or rootbound). Check soil moisture first — if dry, water thoroughly. If moist, investigate humidity or roots. Correct the cause and new leaves will grow normally.
Can calathea grow in air-conditioned rooms?
Yes, with humidity support. AC drops humidity to 40-50%, well below calathea's 60-80% preference. Solutions: humidifier (most effective), pebble tray, grouping plants together, positioning away from direct AC airflow, or keeping in rooms with part-time AC. Many Filipino collectors successfully grow calathea in AC bedrooms using a combination of these strategies.
What is the easiest calathea to grow?
Calathea lancifolia (rattlesnake) — most forgiving of humidity inconsistency. Also beginner-friendly: rufibarba (furry feather), ornata (pinstripe), and roseopicta (medallion). Avoid as first calathea: orbifolia (extremely humidity-sensitive), warscewiczii (demanding), and especially White Fusion (arguably the most difficult common houseplant).
How do you propagate calathea?
Division only — calathea cannot root from leaf or stem cuttings. During repotting, gently separate clumps with their own rhizome sections and roots (minimum 2-3 stems per division). Keep divisions in high humidity for 2-3 weeks. Best done March-October. Do not fertilize for 4-6 weeks after dividing.
