Calathea rattlesnake (Calathea lancifolia) is prized for its long, wavy leaves patterned in deep green spots with rich purple undersides, adding bold texture and color to indoor spaces. It thrives in bright, indirect light, as direct sun can fade or scorch its foliage. Keep the soil consistently moist but never soggy, using filtered or distilled water to avoid leaf browning from minerals. This plant loves high humidity and warm temperatures (65–75°F), making bathrooms or kitchens great locations—or supplement with a humidifier. Fertilize lightly during spring and summer, and reduce watering in winter as growth slows. Pet-friendly and non-toxic, it’s a beautiful, safe choice for homes with animals.
