Embrace seedheads! Many, like buckwheat and sages add interest, even soft colors when there isn't a lot else going on in the garden. (Less work if you don't cut them right off, and seeds are probably food for somebody!)
Space plants far enough apart so they can grow to full size. Most natives don't need a lot of pruning, shearing, and shaping -- some don't tolerate it.

Create interest, even drama, with foliage contrasts, interesting plant combinations, rock and other features. When the whole picture is engaging, who cares about a few untidy bits?

To me, the naturally occurring litter is not so objectionable as are piles of grass-clippings and hedge trimmings. Much less sweeping and raking to do when you leave leaves!
