Hello! I recently bought this plant from a supermarket of all places (seen it and couldn’t resist) but it didn’t have a label on or say what the plant was called. I doubt it’s too unusual seeing as it was from a supermarket but I can’t seem to find it on google. It has got a lot of leaves that are green and quite glossy and red on the underside. I’ve currently got it on my windowsill in direct sunlight so I want to make sure this is the right place for it and how often I should water it etc. Thanks:)
