Which Plant Where is an evidence-based plant selection tool developed by Hort Innovation to help professionals choose appropriate species for urban environments. The tool considers factors such as climate, soil conditions, maintenance requirements, and aesthetic preferences. Originally developed for industry use, it was made freely available to the public in 2023, significantly expanding access to professional-grade plant selection guidance. This resource is invaluable for landscape architects, urban planners, and green infrastructure professionals working on species selection for urban greening projects.
