The garden is often regarded as a feminine space of withdrawal. By contrast, this essay examines how Jamaica Kincaid envisions the garden not as a retreat from the world but as an opportunity to delve into the colonial histories of plants. Kincaid traces the twinned histories of botany and empire, highlighting how the botanic garden served as a laboratory for the development of plantation crops and therefore played a pivotal role in imperial and capitalist expansion. I concentrate on Kincaid’s use of ekphrasis, which reveals the many aesthetic, scientific, and colonial discourses that construct the garden as a both discursive and material space. Kincaid’s ekphrastic prose produces an effect of “overterritorialization,” in which loco-descriptive details do not provide the reader with a sense of place; rather, the overabundance of details overwhelms and even unsettles the reader. Kincaid’s garden writing thus shows us an alternative model of reading postcolonial environmental literature.
