A flowerbed can be attached to a vertical structure, and is thus viewed from only one spot, or it can be isolated, so that you can walk around it and enjoy it from any viewpoint. A parterre is a clump surrounded by a low hedge of an evergreen species (boxwood, pulchelo or rosemary, for instance).

Step by step
First, make a drawing of the area you are going to plant. It will be very useful in planting the flowers later.

Mark the North and draw in the elements close to the flowerbed that will affect it in some way: for instance, a tree that will provide shade in the afternoon, a meadow that will provide moisture, a wall giving protection from the wind or even a rise in temperature, if the wall faces south or west.

Before planting the clump you need to set up an adequate system of programmed watering. This must assure periodic watering with the amount of water that is right for the plants and the season of the year.

Another important factor is to use soil that is loose, permeable and fertile so that the plants will grow to be healthy and vigorous. 

When you plant, allow space for things to grow.

Internal factors such as the structure, color, texture and arrangement of the plants depends on the taste of the person doing the planting, always keeping in mind the aromas you want to come from the garden.

Species with fragrance
There are a wide variety of plants with fragrant blossoms and leaves for just about every time of year. It is very useful to know some of the most common species in this type of groups.

The plants used to create structure (edge or interior of the clump) should be evergreen: myrtle, boxwood, eleagnus, rosemary, lavender, thyme and geraniums are perfect species for this purpose. They can be combined with varieties that blossom in staggered fashion throughout the year, giving rise to attractive arrangements that will look particularly good at certain times of year. Some examples are:
- Spring.- Freesia, hyacinth, lily of the valley or callistephus.
- Summer.- Petunias and Crambe cordifolia.
- Autumn.- Cosmos, Nicotiana sylvestris, Verbena sp and Cent�urea 
- Winter.- Wallflowers or violets. Unfortunately these are the most scarce.

Still, there are some species that bloom almost year-round, such as alder and some kinds of roses.

Also keep in mind which direction the clump is facing because some species like sun in the morning, such as violets, or the sun from the West, like geraniums.

Climbing cover vertical structures. Species like jasmine or honeysuckle fill the air with their sweet smell.

In areas where puddles form, Houttonya cordata covers this up rapidly and takes on a splendid color if it is placed in direct sun.
