When I enter a dark room from a lit room, I initially can't see anything. But given 60-80 seconds, I become able to clearly see the shapes of furniture around me, and even the pattern on the carpet, even though the room is lit only by a couple of indicator LEDs from a router sitting on the top of a closet.
I bet that after a few minutes in a dark room, the petunias will look very visible and detailed. The room has to be dark though; a distant streetlamp through the window would easily overpower a flower.

Awesome that it can be done at all but sounds like the images give an exaggerated impression of the glow.
Human eye accomodates well to darkness.
