About Calathea 'Rattlesnake'

The Calathea 'Rattlesnake' (Goeppertia insignis) is a striking houseplant known for its wavy, lance-shaped leaves patterned with dark green markings and deep purple undersides. Native to Brazil’s rainforest floors, this prayer plant adds tropical flair to any indoor space and folds its leaves upward at night—a beautiful detail that plant lovers adore.

Lighting

Calatheas prefer medium to bright, indirect light. Avoid direct sun, which can cause fading or leaf burn. They also do well under grow lights, making them a great option for lower-light homes or offices.

Watering

Keep the soil evenly moist but not soggy. Water when the top inch feels dry, and avoid letting the plant dry out completely. Use filtered or distilled water when possible, as Calatheas are sensitive to chemicals in tap water.

Temperature and Humidity

Maintain a warm environment between 65°F and 80°F. High humidity is key to keeping Calathea happy—ideally above 50%. Mist regularly, use a humidifier, or group with other plants to create a more humid microclimate.

Feeding

Feed monthly during spring and summer with a diluted balanced houseplant fertilizer. Pause feeding in fall and winter when growth slows to avoid buildup in the soil.

Care Tips

• Avoid cold drafts or sudden temperature changes, which can cause leaf curling or browning edges.
• Wipe the leaves gently to keep them clean and vibrant—dust can block light and slow growth.
• If leaf tips brown, increase humidity and switch to filtered water if you're not already using it.

With its dramatic foliage and rhythmic leaf movements, the Calathea 'Rattlesnake' brings both color and character to any room. It’s a perfect gift for plant parents who enjoy a bit of flair and a touch of the tropics—no green thumb required.
