Ferns - source of truth?

​“Currently, information relating to ferns can be found in a number of places, but there is no single source of truth.”                                                                                                    (aboutferns.org)
 
            Ah! Evidently, the complexity of ferns goes beyond their dazzling geometric beauty.
 
            Ferns clean myriad toxins out of the air. NASA scientists identified several “volatile organic compounds” – VOCs – that sicken humans in enclosed spaces like Skylab or a well-sealed building. Once plants are introduced, voila! Cleaner air, healthier humans. Among plants, ferns are an air cleaning champion.
             
            Is that why I love to witness their annual uncurling, walk through them, sweep my hands along their feathered spines? Do they hold a precious secret? Might we find intricate layers of truth amongst the ferns?
