How Orchids Inspired the Groundbreaking Work of Charles Darwin
Nestled within the tarmac lasso around London formed by the M25 motorway but feeling very far in time and space from the city, Charles Darwin’s home, Down House, has a spooky quality: it feels like he just popped out. His
Charles Darwin's passion for orchids profoundly influenced his groundbreaking scientific work. His home, Down House, in London, retains an air of familiarity, as if he never left. The office is filled with correspondence, open books, and specimens of insects and fossils, while a wooden slide allows children to slide down the staircase.
The presence of his children is still felt through the mulberry tree and the orchids in the garden, which were grown by Emma, Darwin's wife. The Sandwalk, a path where Darwin would pace daily, is lined with woodland that he planted himself. It is within these woods that Darwin discovered the violet helleborine orchid (Epipactis purpurata), which he studied to understand insect pollination.
Darwin's fascination with orchids led him to predict the existence of a moth with a tongue long enough to reach the nectar at the base of an extraordinary orchid. This prediction was fulfilled decades later when a moth with such a tongue was discovered in Madagascar, earning it the species name praedicta. Darwin's observations of orchids' deceptive behavior and their relationship with fungi shed light on the intricate pollination mechanisms of these flowers.
