Jean-Jacques Rousseau's interest in botany has a complex genesis. I propose to investigate the varying contexts in which this interest arises over the course of Rousseau's life and works. His initial discovery of botany is first recounted in The Confessions: it was at Les Charmettes, the central locus of the author's childhood, where he enjoyed the happiness and protective company provided by Madame de Warens, the woman he simply called Maman. However, this interest proves to be brief, a missed opportunity of sorts, and botany becomes a catalyst for a flood of happy memories associated with a previous time, in Annecy. Indeed Rousseau becomes less engaged in the act of recalling botanical lessons (he hardly makes any effort in the description of the structures of the plants themselves) than in releasing the power of affective memory. Thus Annecy and Les Charmettes overlap in Rousseau's imagination. The botanical walk becomes the setting for the recollection of a dream experienced earlier at Annecy, a reverie in which Jean-Jacques's union with Madame de Warens remains suspended in eternity. He writes:

Another scene deserves mention, also in The Confessions, one in which botany provokes a kind of revulsion in Rousseau.
