Cast Iron Care Guide
The Japanese cast-iron plant (Aspidistra elatior) is a perennial from sun to shade and attracts few pests, making it one of the easiest of indoor plants to care for. It is tolerant of a wide range of soil conditions and atmospheric pollutants. This tough houseplant gets its nickname "cast-iron plant" from its reputation for being an easy keeper.
The Cast Iron plant prefers low to medium, filtered or indirect light. These plants will tolerate almost any light conditions, however, direct light must be avoided.
This plant prefers to dry out by at least 50% in-between waterings. The Cast Iron plant will do well with a standard, well-draining potting soil. Adding perlite, bark, lava rock or pebbles to your growing medium will help to add drainage and soil aeration.
The Cast Iron plant is not picky about temperatures, and they can withstand pretty cold temperatures. However, when growing indoor plants, it is best to try to maintain a consistent environment. Temperatures between 60 and 80 degrees would be considered ideal. This plant is hardy when planted outdoors in USDA zones 6 to 11. While this plant would be very appreciative of moderate to high humidity, it does not require it.
