Fun Facts
- 🌱 The common name 'cast iron plant' originates from the Victorian era when these plants were popular because they could survive the harsh, dry, poorly-lit conditions of Victorian homes with coal-fired heating.
- 🌱 The 'Milky Way' cultivar was named for its constellation-like white speckles on dark green leaves, which become more pronounced and dramatic as the plant matures and receives appropriate light.
- 🌱 Aspidistra species are native to subtropical regions of China and Japan, where they grow on the forest floor in shaded, protected locations—explaining their preference for indirect light.
