The escalating biodiversity crisis, coupled with the increasing frequency of droughts and anticipated water shortages due to climate change, necessitates a shift towards biodiversity-led landscape architecture, including domestic gardens. Traditionally viewed as high-maintenance spaces emphasising tidiness, domestic gardens can significantly impact urban green infrastructure and species richness. This paper explores the concept of ‘savage gardens’—untamed and natural spaces representing a fourth nature approach, incorporating wild gardens and neglected areas. Despite potential challenges in public appreciation, it is argued that savage gardens offer substantial benefits, such as reduced maintenance, increased biodiversity, and enhanced resilience to climate change. By reframing the perception of ‘savage’ from biophobic to a reconnection with nature, savage gardens are proposed as a viable solution for balancing aesthetics, maintenance, ecosystem services, and biodiversity in domestic landscapes, promoting a more sustainable future in the face of the biodiversity emergency.
