Care recipient friendly landscaping

Something else that I am trying to take into consideration are placements on things like statues and flowers. I want them to be where my dad can see and enjoy them rather than have them tucked out of his view.

It makes no sense to landscape a part of the yard that will hardly be seen, so I will focus mainly on where I know my dad will be able to enjoy it even if me and mom are not going to be spending time in that area. Particularly if mom and me won't be in that area. I also want to fix the garden so he can sit back there while me and mom work in it.
