Not every plant reflects the same amounts of infrared light. Leaf shape, sun exposure, size and photosynthetic activities make the difference in light reflection. Plants use infrared light to communicate: are some plants shouting and others whispering?
Enjoy this infrared tour in the tropical and desert greenhouses of Zürich botanical gardens: white means presence of infrared, black means none.
Cactaceae and yuccas strongly reflect infrared.
Infrared transparencies of hanging plants
Shadows from leaves and roots: with infrared photography black and white borders are highly contrasted
