Those of us who are not visually impaired tend to plant for colour and design, utility or wildlife value - scent is often an afterthought, a fortunate by-product of our choices. In contrast, all of the plants in 'Fragrant Plants' have been chosen for their scents.
The book has a short introduction and then leaps right into the plants, with fragrant flowers divided by the season in which they flower. Each plant has a column headed with a photograph and containing everything you need to know to be able to grow it, including how easy it is and where the plant is best used. Many of the plants chosen have been awarded the RHS Award of Garden Merit, meaning that they are easy to find and should grow well in most gardens.
Between 'Spring' and 'Summer' there are several pages on choosing and growing scented roses, which are a perennial favourite. And once you're past 'Winter' you'll find a section on aromatic plants - plants which don't necessarily have scented flowers but which release a scent when touched or crushed. Many of these are culinary herbs, and are marked as such; these entries are shorter and there are fewer photographs.
The back of the book covers the basics of gardening and growing plants. It reminds us that flowers with pleasant smells are aiming to attract beneficial insects (bees, butterflies, beetles and moths). The topics covered include planning and sourcing plants, caring for them, hardiness, pest and disease problems and propagation.
Four pages at the back list plants that are useful in different settings and for different things - e.g. groundcovers, full shade or with flowers in particular colours. One omission seems to be a list of plants that release their scents in the evening, a topic that would be of interest to gardeners who aren't fortunate enough to be in their garden most days.
