Which brings us to the idea of a garden as an illusion, for it is the constant hope of the gardener that enriching this bed and plating that shrub will result in an aesthetic experience that lives up to the dream. So, what is the gardener's dream but a dream of the ideal order in which beauty can be expressed and loss absorbed? Often the struggle between what is hoped for and what is accomplished meets with unexpected disappointments: weeds and varmints are insistent, a flower bed looks poorly. But as the gardener moves along with worried brow, suddenly the smell of a particular flower provides transport to a garden from one's childhood...Memory is awakened, the world made whole, if only for a moment. But in that moment some sort of healing takes place, or so gardeners have believed for centuries."
