Gardens are a place of gathering for people and pollinators. Scents and chemical signatures are Mother Nature's guiding hand that encourage bugs to select a particular plant for pollination. Another powerful benefit is tied to our own olfactory sense in such a way that certain fragrances are known to encourage relaxation and over all well being. We suggest placing sweetly scented plants throughout your space to invoke a pleasant ambiance. For those reasons providing scented plants is highly recommended.
