This blend file is an extension of the project file - Parametric Variations Of Instances, Geometry Nodes, Blender 3.4+ - available here:

Parametric Variations of Instances, Geometry Nodes, Blender-3.4+

This blend file showcases a workflow to assemble a single node tree which will generate multiple parametric variations of an object or a geometry & then scatter them at VERTICES OF A MESH. In the example shown in this file, each of the 505 vertices of suzanne mesh have a parametrically different variation (both in modeling & shading) of the flower object. Each flower object is aligned to the vertex normal. 

This setup works for Blender 3.4+.

This setup eliminates the need for any collections, animation or simulation.
