Now this is one cool plant you won’t find anywhere else. I found these totally by chance while shopping for some other plants. Despite the name, this unusual cultivar of Cast Iron plant is believed to have originated from Vietnam. Like other Cast Iron plants, the Singapore Sling can tolerate neglect and thrive in the darkest shade you can throw at it. It’s the tallest of the cast iron plants and can grow to about 3ft with narrow 1-2” leaves which are mottled with striking creamy white spots. If you want something really unique which nobody else has, this is the plant for you. He had only 4 of these plants are available in 6” pots.
