Calathea 'Rattlesnake' Care
Calathea ‘Rattlesnake’ (Goeppertia lancifolia)
Overview
- Long, wavy leaves with bold dark green patterning
- Purple undersides add contrast and depth
- Rhythmic leaf movement in response to light
Calathea ‘Rattlesnake’ is a striking foliage plant known for its elongated leaves marked with alternating light and dark green patterns. The rich purple undersides create contrast, especially as the leaves lift and lower throughout the day.
Origins
Native to the tropical forests of Brazil, where it grows along the forest floor in consistently warm, humid, and shaded conditions.
Light Requirements
- Prefers medium to bright, indirect light
- Tolerates lower light, though growth may slow
- Avoid direct sun, which can fade or scorch leaves
Watering
- Keep soil consistently lightly moist
- Allow the top inch of soil to dry slightly between waterings
- Use filtered or distilled water when possible to prevent leaf spotting
Humidity
Prefers high humidity (60%+). Dry air can lead to browning edges and curling leaves.
Temperature
- Ideal range: 65–80°F
- Avoid cold drafts and temperatures below 60°F
Soil
Aroid Mix. A moisture-retentive but well-draining mix supports consistent hydration without waterlogging.
Fertilizer
Feed every 4–6 weeks during spring and summer with a diluted balanced fertilizer. Reduce feeding during fall and winter.
Preferred Growing Method
Potted display. Best placed in stable environments away from vents and drafts.
Final Notes
Calathea ‘Rattlesnake’ responds best to consistency. Stable moisture, elevated humidity, and gentle light will maintain its patterned foliage and overall structure.
