I’ve taken to the wonky unusual plants of late as I pretty much have all the Aroids (well, many many). This plant is growing in my living room in roughly 55 to 58% ambient humidity. Light is indirect from a south window, blinds down, with supplemental grow lights. I keep it wet per Don Ivan, and it’s doing really well. I have a Zamorana next to it and it’s also doing just as well.
