What are ferns used for?
Ferns are not of major economic importance, but some are used for food, medicine, as biofertilizer, as ornamental plants and for remediating contaminated soil. They have been the subject of research for their ability to remove some chemical pollutants from the atmosphere.
Why are ferns so special?
Ferns are unique in land plants in having two separate living structures, so the ferny plant that we see out in the bush produces spores, and those spores, when they are released, don’t grow straight back into a new ferny plant. They grow into a little tiny plant that we call a gametophyte.
