In many Western societies, botany is thought to be a wearisome and outdated branch of biology. Unlike animals, plants awaken little or no interest. This tendency has been interpreted as a condition inherent to humans and was named "plant blindness," with negative consequences to teaching and research in biology. In this article, we examine the orig...
