Within the depth-psychology corpus, ‘blossom’ functions as a dense symbolic node rather than a merely decorative image, carrying weight across vegetative mythology, alchemical symbolism, mandala phenomenology, and process philosophy. Neumann is perhaps its most rigorous theorist, treating the blossom as the luminous apex of a vegetative cycle that enacts the deepest feminine mysteries — a movement from seed through root and stalk to radiant flowering, and thence to concentrated fruit, each stage encoding the Feminine’s transformative power. Jung independently recruits the blossom as a synonym for the mandala flower of light, particularly in his engagement with the Secret of the Golden Flower, where a ‘blossom growing from a plant’ in brilliant fiery colours carrying ‘the blossom of light at the top’ is read as a psychic symbol of the germinal centre of consciousness. The alchemical tradition, as explored by von Franz, assigns ‘flos’ a technical role as the mystical transforming substance — flowers as blossoms of the spirit bedewed by the Holy Ghost. Campbell maps the blossom onto the threshold of crucifixion and redemption, noting that where spring’s blossom once grew, corruption follows — yet beyond that threshold lies beatitude. McGilchrist draws on Hegel’s bud-blossom-fruit triad to argue for the equal necessity of all moments in a living whole. The term thus hovers between vegetal archetype, alchemical operation, mandala symbol, and processual metaphor for psychological transformation.
