It is caused by the cell walls in leaves and plants reflecting the infrared light and it is being detected by the night vision camera. Normal color cameras have a filter that blocks night vision and the infrared light so the leaves and plants do not glow. It is a trade off, all night vision cameras depict plants glowing in direct sunlight but allow you to see under little or no light conditions.
