The Nobel committee expressly mentioned this work in their nomination of Maeterlinck for the greatest of all literary prizes (awarded 1911): "L’Intelligence des fleurs [The Intelligence of Flowers], 1911…is interesting for its bold representation of plants as having wisdom and self-interest. Here one finds the same richness of poetic imagination and, occasionally, profound reflections."
