Here is a budget-worthy design with a simple but carefully constructed plant palette.  It can be placed as a focal point near an entrance, at the end of a drive, or, in front of a grouping of shurbs that will provide a background.  This plant composition will provide a sequence of flowering episodes from July through September. It will also attract hummingbrids, butterflies, bees and other beneficial insects.  Many of the perennials are prolific flowering species with airy, cheerful and graceful habits.  Give this garden its own location, or, combine with others around your property to orchestrate a perennial ' concert' at your site.
