Philodendron mamei, mature leaf pattern

My vote's with you - Calathea

Same plant. I've seen these before, but usually in a hothouse setting.

And if not Philo mamei, maybe P. Plowmanii (see pic)

I've seen that picture before! I figured it was a Calathea orbifolia, too. But think of all those poor Pinterest users out there who think they can grow a hosta like that...

Pinterest is riddled with un/misidentified plants. As you say, pity the naive user.

Just came across the same pinterest photo and had to google it as the coolest looking hosta ever. I was wondering if anyone had ever genetically modified a hosta to glow in the dark as they do glofish, YET!

It's a calathea orbifolia
