I have a perennial garden bed in silver, green and flowers in all colours of the summer fruits - strawberry, raspberry to cherry and blackberry. Palest pink perennials to plum-black tulips, all in a bed given structure with 5 green spheres, that is to say, vegetable balls, all in a row.
About a year ago I was thinking about adding grasses for a meadow-like effect (above, the meadow at Great Dixter, Sussex) and consulted he-who-works-in-conservation. Would kangaroo grass (Themeda, below) pass the (conservation/non-weedy) test? It would. Would kangaroo grass be tall enough, upright and defining, adding a definite new element? We'll see. It took us a while to visit our local indigenous nursery (the wonderful Birdsland) and choose about 6 plants in little tubes.
Will it make an Australian meadow? Probably not; there's so many exotics: bulbs, perennials...although at least my green spheres are of one of the new dwarf native rosemary (Westringea) cultivars.
But could I make myself plant the grasses randomly? Well, no.
