- The Calathea lancifolia is an attractive tropical houseplant with slender pointed leaves decorated with light and dark green patterns. It produces lance-shaped leaves with dark ellipse patterns on the upper side and purple colours on the underside.
Light Required Calathea lancifolia is not a big fan of direct sunlight. It is, therefore, best to place your Rattlesnake plant in a shady spot with indirect sunlight. Too much sunlight can cause several problems such as brown or crispy leaves.
Watering You should water your Calathea generously from April to October without causing stagnant moisture. In colder months, you should keep the potting soil a touch drier. It is best to either use lime-free water or rainwater.
Best Growing Conditions Don’t place your Rattlesnake plant near vents or any other air source because it is very sensitive to sudden changes in temperature.
