This essay argues that Leslie Marmon Silko's 1999 historical-fiction novel Gardens in the Dunes enables Indigenous-centered interventions into Victorian studies, ecocriticism, and their intersection. Dramatizing an animistic Native American view of nature as agentic and enspirited, Silko's novel critiques Victorian plant hunting as rooted in settler-colonial logic that treats nature as inert. In turn, through representations of late Victorian gardeners, Silko suggests that British horticulture was also informed by colonial and capitalist ways of thinking about plants. At the same time, however, the novel locates an animistic strain running through Victorian gardening discourses, which I demonstrate through readings of Victorian garden books depicting plants as agentic and enspirited. Silko, I argue, invites us to revisit the late nineteenth century as characterized by a cultural revival of animistic thought, even as this period also saw the racist stigmatization of animism in the field of Victorian anthropology. I connect this fraught discursive moment in British history to an inherited hesitation toward animism in contemporary Victorian studies and ecocriticism, a hesitation that has contributed to uneven engagement with Indigenous thought in both fields. In response, this essay explicates and emulates Silko's critical methodology for an undisciplining engagement with animism in white-authored, ecocritical Victorian studies.
