Goeppertia insignis - Calathea, Prayer Plant, rattlesnake plant

Commonly Known as: Rattlesnake plant, prayer plant, rattlesnake calathea

Care Information: Filtered light is the best option. If you want to place your rattlesnake plant in a window, select one that doesn't have intense afternoon sun streaming through it, or diffuse the light with drapes. A bright spot in a well-lit room works well. Choose a well-draining soil. Although these plants can't handle standing water, they like to be kept moist. A light sandy soil or a potting mix of two parts peat moss and one part perlite works well. Rattlesnake plant prefers slightly acidic or neutral pH levels, but alkaline soils should be avoided. Over the summer, when your rattlesnake plant experiences the most growth, it needs to be watered frequently to keep the soil or potting mix moist. During the winter season, allow the top layer of soil to dry out before watering again.Rattlesnake plants don't tolerate waterlogged conditions; if the leaves start to turn yellow, you may be overwatering. Conversely, if the leaves begin to curl unattractively they aren't receiving enough water.Frequent small waterings are required rather than deep irrigation. Water the plant until it just starts to trickle out of drainage holes (do not water so much that it is streaming out of the bottom). Do not let the plant sit in the excess water. Pour the excess water out and do not pour it back into the plant.
