Planting Culture designates, within the depth-psychology and comparative mythology corpus, a complex of mythopoetic, ritual, and psychological forms that arise from agrarian, horticulturally organised societies and stand in sustained contrast to the mythologies produced by hunting peoples. Campbell is the primary architect of this concept in the library; he treats Planting Culture as characterised by communal integration, cyclical cosmologies centred on death-and-renewal, and a ritual grammar in which the slaying of a divine being (the dema deity) underwrites agricultural fertility. Where hunting mythologies privilege the visionary individual — the shamanic faster who receives personal spirit-power — planting mythologies subordinate the individual to communal ceremonial order, aligning human life with the cosmic rhythms of seed, growth, harvest, and decomposition. Eliade amplifies this dimension, reading Earth-Mother fecundity rites as expressions of the mystery of generation that anchors religious experience in agrarian worlds. Jensen, cited by Campbell, identifies the ‘first killing’ as the generative violence at the heart of planting-culture rite. The concept intersects with Neolithic diffusion theory, questions of Old World versus New World parallelism, and the broader psychocultural distinction between societies oriented toward individual transcendence and those structured around collective, chthonic participation. Its depth-psychological significance lies in the claim that the psychological types fostered by planting versus hunting economies differ fundamentally in their relationship to ego, community, and the sacred.
