Flora Unveiled

Sex in animals has been known for at least ten thousand years, and this knowledge was exploited during animal domestication in the Neolithic period. In contrast, sex in plants wasn’t discovered until the late seventeenth century. Even after its discovery, the sexual “theory” continued to be hotly debated for another 150 years, pitting the “sexualists” against the “asexualists.” Why was the idea of sex in plants so contentious for so long? In answer, Flora Unveiled offers a deep history of perceptions concerning plant gender and sexuality, from the Paleolithic to the nineteenth century. Evidence suggests that an obstacle far beyond the mere facts of pollination mechanisms stymied the discovery of two sexes in plants, and then delayed its acceptance. This was a “plants-as-female” paradigm. Flora Unveiled explores the sources of this gender bias, beginning with women’s roles as gatherers, plant-textile makers, crop domesticators, and early horticulturists. In myths and religions of the Bronze and Iron Ages, goddesses were strongly identified with flowers, trees and agricultural abundance. During the Middle Ages and Renaissance, this tradition was assimilated to Christianity in the person of Mary. The one-sex model of plants continued into the Early Modern Period, and staged resurgences during the eighteenth century Enlightenment and in the Romantic movement. Not until the nineteenth century, when Wilhelm Hofmeister demonstrated the universality of sex in the plant kingdom, was the controversy over plant sex finally resolved. Flora Unveiled chronicles how persistently cultural biases can impede discovery and delay the acceptance of scientific advances.
