The plant world is fascinating. Approaching the study of botany is something truly magical and is loaded with symbolic connotations, many of which have been maintained to this day through time. On occasions, these mystical-fantastic narratives keep within them the atavism of ancestral or rudimentary knowledge. In others, on the contrary, they end up generating hoaxes. This work aims, precisely, to get to the root of many of those myths, hoaxes and legends linked, in one way or another, to the plant kingdom. Throughout its pages and with the help of a powerful scientific tool, botany, the author will answer questions such as when did Christian floral symbology emerge or what is hidden behind the terrifying Japanese creature known as jubokko. Likewise, it sheds light on hoaxes such as the consumption of substances considered aphrodisiacs, whether or not blind people can practice botany or even whether the statement that a squirrel could cross Spain jumping from tree to tree is true or not.
