The little Ping has developed a few carnivorous leaves. From their size, it seems to be a very young plant, which I am totally fine with.
Given that its natural habitat is very sunny (see above introduction), I tried to get it accustomed to direct sunlight. While it suffered from no apparent sunburn, the foliage went from pretty pink to pale orange, and more importantly, it almost stopped growing. So I took the plant back indoors near a south-facing window, with lots of light but no direct sun. In its habitat, it most probably gets some shade from the tall grass that grows around it.
I potted the plant in a 100% mineral soil composed of perlite, vermiculite and fine sand, in equal parts, with a topping of quartz gravel. The plant is still in the winter, small-rosetted stage.
