Calathea lancifolia is a wonderfully showy houseplant. It has upright, lance-shaped leaves with long wavy edges that form in clumps, spreading slowly over time. The leaves are variegated with dark green strokes on a pale green background. The undersides are a burgundy red and velvety to the touch. The Rattlesnake plant is also sometimes known as Calathea insignis.
 
Calathea lancifolia is a moderately fast growing plant, ultimately reaching heights of around 60cm.
 
Light:
As with most variegated plants, Calathea need plenty of diffused light. Direct sunlight will cause the leaves to fade and lose their markings. They can tolerate some degree of shade, but the more indirect light, the finer the foliage.
 
Watering:
Calathea must be kept in damp soil at all times, but definitely do not allow the plant to sit in water or in very wet soil. 
 
Temperature:
Prefers warm to high temperatures, ideally between 18-23°C, but can cope with as low as 15°C. Avoid draughts and ensure the plant has reasonable ventilation.
 
Humidity:
High humidity levels are a must. Mist frequently to improve humidity conditions and pop it near the shower or in the kitchen from time-to-time to give it an extra boost.
 
Feed:
Apply a weak dose of a nitrogen-rich foliage fertiliser once or twice a month during the growing season.
