- History & LoreHistory:This fern is native to a huge range spanning much of the Northern Hemisphere. This species is a commonplace wood fern in Europe and is also found in scattered locations in North America. It prefers to grow in limestone areas. The genus was classified and named by Austrian botanist Heinrich Schott. It is found in oak forests of Europe, which explains the translation of its name from the Greek for oak fern.Lore:In ancient Europe, ferns were often associated with incantations and spells granting one invisibility because the plants lacked seeds and seemed to magically appear. Male fern is grown commercially as an anthelminthic, to expel worms.
