Plants evolved under dim red dwarf suns or in more distance habitable orbits around a brighter star may appear black to Human eyes because they would probably need to absorbing more parts of the visible wavelength range to more effectively exploit as much of the available light as possible. Indeed, some in particularly dim environments may also evolve to use energy from infrared or ultraviolet radiation to power photosynthesis.
