Calathea Orbifolia

The Calathea Orbifolia is one of the most spectacular tropical houseplants. Its round leaves, pale green striped with silver, can reach 30 cm across. It’s also a “prayer plant”: the leaves fold vertically at night (a phenomenon called nyctinasty).

But beware: it’s a demanding diva. Tap water that’s too hard, dry air, drafts, direct light — every one of these triggers irreversible browning of the edges. Reserved for plant parents with some experience.

What you really need to know

Requires high humidity, filtered or rain water, and a thermally stable spot. Not a beginner plant, but with the right care it becomes a stunning companion. Beginners should rather check our easy plants list.

Light

Medium to bright indirect. No direct sun (it bleaches the leaves and burns the edges). Ideal behind a sheer curtain in an east- or north-facing room. In low light, variegation fades.

Watering

Every 5 to 7 days during growing season, spaced out in winter. The substrate must stay slightly moist at all times without ever being soaked. Use filtered, distilled or rain water exclusively: chlorine and limescale brown the leaves within weeks.

Humidity and temperature

Critical. Aim for 60-80 % humidity: a humidifier is almost mandatory in winter. Temperature 18-24 °C, never below 15 °C.

Mistakes to avoid

• Tap water: brown edges guaranteed within 2 months
• Dry air + nearby radiator: leaves curl and dry
• Drafts: sudden leaf drop
• Direct sun: permanent variegation bleaching

Toxicity

✅ Non-toxic to cats, dogs and children. Ideal for pet households.

Propagation

By division at repotting (spring), separating rhizomes with roots on each section. Water cuttings don’t work for Calatheas.
