Mine tends to the 'let it all grow all over each other' style, with an attempt at some repetition of colour and variation of shapes, but basically it does what it wants. I think it does keep down weeding, and gives a more naturalistic look. I do have some friends who don't like the way I do it so much, and that is fine, they are still friends! I don't want to see any bare ground, but if there is some, then a pot of something will go there to keep the growth fairly solid. It is not necessarily the easy kind of gardening some people think, but that was never the point. My original aim when we came here, was out small 'lawn' should be secluded and surrounded by huge amounts of flowering plants and trees - we are getting there.
I find the herbaceous clematis very good in this kind of garden, as they happily creep over just about everything without actuually climbing. Lots of hardy geraniums, grasses and so on.
The second part of the garden is the working part, veggies, fruit cage, strawberry beds, shed and greenhouse, just as lovely in its own way.
There are pots absolutely everywhere, including what would be a patio if we used it as such. Our predecessors put it where it is, but it is the cooler, shadier side of the house, so as a place for many hosta pots, and other things it serves our purposes well.
