Maxtree once again shares a few 3D models of plants from their latest release, with 6 different variations for a peach tree and 9 for a trailing abutilon.
You can get both models in native format for 3ds Max and Cinema 4D, V-Ray and Corona Renderer, and universal extensions (.OBJ and .FBX).
Get the files for the peach tree here, and for the trailing abutilon here.
