I played around with geometry nodes.This setup makes it quite easy to have different kind of flowers with a different density at the locations of selected objects (see the parameters in the modifier on the right). For the size of the flower patch you need to delve into the nodes. I might figure out something easier for that.
On the art work I saw two main locations for flowers. I appended some geometry from the latest block out. It was quite a surprise (maybe a little disappointing as well) with how tiny the flowers are from the camera view. They are not that noticeable.
@spikeyxxx and @rstich is this workflow going to work together with your grass workflow?
