Just got this from a local shop. Language barriers prevented instructions and info. I think it could be a fiddle leaf, but this one has darker stripes I'd love to know which plant is this, and how often should I water it?
I'd imagine someone will come along who knows more specifics, but this is not a fiddleleaf fig, if that's what you were thinking. It looks to me to be related to Calathea or something else in the Marantaceae family.
I don't know the ID either, but agree that it is not a fig. Is there a hole at the bottom of that pot? If not, it will be very difficult to care for it properly. If there is a drainage hole, after you water it and no more water comes out the bottom and you have removed water from the saucer, feel how heavy it is. When it looks dry on top, and feels dry and is dry even below the surface, feel how much lighter it is. Water it when it feels that light.
Chinese evergreen is Aglaonema spp. It is somewhat more tolerant of drought and chill. Calathea spp. is more in need of humidity and warmth.
