Calathea Rattlesnake (Goeppertia lancifolia) is a striking prayer plant prized for its long, wavy leaves adorned with dark green ovals on a pale green background and deep purple undersides. This Brazilian native adds an exotic touch to interiors and its leaves fold up at night, making it a dynamic houseplant. Non-toxic to pets and people, it also helps purify indoor air.

Key features:
- Distinctive lance-shaped leaves with dark green elliptical markings and purple undersides.
- Nyctinastic movement – leaves curl up at night and unfurl by day.
- Non-toxic and safe for cats, dogs and humans.
- Natural air-purifying qualities.

Care instructions:
- Light: Provide bright, filtered or indirect light and avoid direct sun to prevent leaf scorch.
- Water: Keep the soil evenly moist but not soggy, watering when the top 1–2 in (2.5–5 cm) of soil dries out; use filtered or distilled water to prevent brown tips.
- Humidity: Prefers high humidity above 60%; ideal in kitchens or bathrooms or on a pebble tray with water.
- Temperature: Maintain temperatures between 65–75 °F (18–24 °C) and protect from cold drafts.
- Soil: Use a well-draining, peat-based potting mix amended with perlite or vermiculite.
- Fertilizer: Feed monthly in spring and summer with a diluted balanced houseplant fertilizer, and refrain from feeding in winter.
