Hi Keith,
Thanks for the reply.
I will make few changes in hardscape, but I'm going to leave the central pathway for now. It looks straight and not natural now, but after all plants planted it should look more natural.
I'm going to plant the whole area with Micranthemum Monte Carlo and Eleocharis Parvula along pathways. I might introduce few small plants around the stones later, after a dry start, but will try to leave it simple.
