Using Scented Plants

Scented plants are used in two ways:

1. Grown in the garden, they offer a bonus over other plants in that not only do they provide the benefit of flowers and foliage like any other plant, but they also have a scent. It should be noted however, that some people can be allergic to the scent of certain plants, and this can therefore be a severe drawback when using such plants in the garden. They are a delight to many people but an irritant to others.

2. The scented parts of the plants can be harvested and used in crafts, perfumes, or other products. They are also ideal for use in sensory gardens for people with special needs, as well as for children.

Types of scented plants
There are many ways you might classify scented plants:

  • By plant part: scented flower, scented foliage, scented fruit, scented root, and so forth
  • By plant group: scented bulbs, scented climbers, scented trees, scented shrubs
  • By type of scent: strong scent, subtle scent, sweet scent, foul scent
  • By use: edible herbs, plants for landscape use, for use in perfumes and cosmetics
  • By plant family: plants which have similar botanical characteristics.
Scented Climbers
Two of the most popular scented plants are Jasmine and Honeysuckle.
Both are climbers; and under the right conditions, their scent can be extremely intense; even overpowering. For some people, the air born chemicals released by these plants can cause a bad allergic reaction; which is something that should always be kept in mind when deciding to grow these plants. Too much jasmine or honeysuckle can be a problem for people who suffer badly from allergies, particularly if planted in large quantities near to a residence or workplace, where those people are unable to escape the scent.
The choice of species or cultivar may also be of significance as well. The sent of all jasmines is not the same. Not all honeysuckles have the same intensity or type of fragrance either.
