Using all the variations of mesh, flower and leaf combinations, this will give 1,000's of individual creations.
Most of the textures used are 1k resolution. For greater performance, you can restrict their size to 256x256. Each leaf and flower is supported by 2 polygons. Prefabs of every mesh, combined with a chosen selection for both Flower and Leaf, is available.
