Hedge It is a Blender add-on from Blender Bits, based in Cornwall, UK. It is built around hedges, bushes, branches, leaves and vines, with related themes spanning nature, garden and ArchViz work.
Compatibility spans Blender 4.0 through 5.0, and the tool is distributed as a Blender extension and add-on. It renders in both Cycles and Eevee, so it fits either render workflow. Documentation is included with the add-on, and it is released under the GPL license.
On superhive, Hedge It has been published for over a year and holds a 5-star rating from three reviews. A demo video is available for the add-on. The catalog lists it as free here, though current pricing, licensing and download details are best confirmed on the developer's page.
