Calathea 'Thai Medallion' is a gorgeous plant. If you know by now, there are numerous version of this species, so we have decided to just put the country where this particular pattern is from. This one is from Thailand, hence the Thai word on its title. Yes, there's also Calathea medallion PH version but don't worry, we are as confused as you are. haha!
Light: Bright, strictly indirect sunlight.
Water: Water only when the top soil is dry. Don't this plant dry out or it'll fold longer. Don't let it sit on water, because the roots will rot, and it'll surely die the next day. Scaaary!
