A Midsummer Night’s Dream abounds in plant life. It refers to between thirty and forty separate plants or flowers, and it has characters named Peaseblossom, Mustardseed and Quince. There is a modern rose called A Midsummer Night’s Dream, and one of the plants in the play has become so famous that it has acquired virtually a life of its own: on February 14, 2002 The Daily Telegraph ran an article explaining that the plant-based love potion used by Oberon on Titania, Lysander, and Demetrius wouldn’t actually work, as if anyone had ever seriously supposed that it might. In this essay I argue that just as the wood outside Athens demarcates a border between the city and fairyland, so the plants found in the wood also belong in two spheres, the scientific one of botany and the mystical one of fairylore; if the naturalist John Gerard is one of the play’s godfathers, the historian and antiquary William Camden is the other, since there is a potential parallel between the way plants are figured in the play and Camden’s interest in plants connected with Roman remains such as the Roman nettle and the Roman Wall plant.
