Here are the best ways to achieve optimal fragrance in your garden is to plant:

By the house
Close placement to the house allows you and others to enjoy the fragrant aroma from inside the house as well as in the garden.

Near a sitting area
You'll detect scents better when you are sitting still to let the aroma of the flowers surround you. Include different pots of fragrant plants on decks, porches, and patios. Allow those vines full of beautiful aroma to wind up porch pillars or trellises near your favorite outdoor chair.

By the wall
The reflected heat from a wall or patio can intensify the odors from many plants, giving you more smell for fewer amounts of flowers.

Beside an entry
Place fragrant flowers next to entry ways to welcome your guests to your home. Plus, every time you leave the house you will enjoy the smell.

Around your nose
Plant fragrant flowers up in window boxes, tall planters, raised beds, or pots on tables, steps, or stands. This will increase the aroma, the closer they are to your nose.

Outside a window
Strongly scented flowers that produce enough scent to come indoors when the windows are open will create a nice feel from inside the house. These are great for a bedroom window: Oriental lilies, lilacs, Daphne, jasmines, and gardenias.

In a mass
Planting one lily plant won't have much effect, but a dozen or more will definitely enhance the smell. The more the merrier.

Underfoot
There are a number of wonderful fragrant herbs that can contribute to your flower garden. Choose low growing herbs, such as thyme and mint, to plant next to flagstones or other places where they're likely to be stepped on which will release their pleasant aromas.

Enclosed space
If fragrant plants are set out in the open yard, the wind can take away the scent. Provide an enclosed space, such as a courtyard that will allow the fragrance to collect and intensify.

Lilacs, fragrant roses, Oriental lilies, hyacinths, Daphne, jasmines, and sweet autumn clematis, citrus trees, many orchids and a variety of herbs are great for releasing wonderful fragrances.
