Grey Star
Ctenanthe setosa
Grey Star is a prayer plant with elongated lance-shaped leaves that look silver-grey on top with dark green veins. Deep purple or burgundy undersides show when the leaves fold upward at night. High humidity and filtered water keep the edges soft instead of crispy.

Pet Friendly
Ctenanthe setosa is considered non-toxic to cats, dogs, and horses, making it an excellent choice for pet owners.
Care Notes
Light
Bright, indirect light keeps the silver tone clear. Direct sun can scorch leaves and fade the pattern. Lower light slows growth and dulls the silver look.
Water
Keep the soil evenly moist, not soggy. Water when the top inch feels dry. Distilled, filtered, or rainwater helps prevent brown tips from chlorine and fluoride.
Soil
Use a moisture-retentive mix of peat or coir with perlite in a planter with drainage holes.
Humidity & Temperature
Aim for humidity above 60% with plant grouping, a pebble tray, or a humidifier. Keep temperatures between 65°F and 80°F (18°C-27°C), away from drafts, AC, and heater vents.
Common Issues
Curling leaves usually mean underwatering or very dry air. Yellow leaves often mean overwatering. Brown edges typically come from dry air or tap-water minerals.
