A lake in the middle of a meadow
Technical note - while the grass, bushes and weeds are scattered using the usual distribute points + instance on points method the flowers and rocks were scattered using Blender's geometry node hair system. The advantage of this system is it allows more precise control of the placement and size of the instances without needing the surface to have lots of vertices. The downside is that it's slower so it isn't suitable for covering large areas.
