The reason why flowers are fragrant is because they contain aromatic oils. Because the aromatic oils of each flower evaporate to different degrees, the flowers have different fragrances. There are also some flowers that, although they do not have aromatic oil, will produce aromatic oil during their metabolism, so they will also have fragrance.

1. The reason for the fragrance of flowers

Some flowers have fragrance, and some flowers have no fragrance. That is because the flowers with fragrance contain a kind of aromatic oil, which volatilizes through its own metabolism. When it comes out, it becomes the fragrance of flowers that we smell.

2. The difference between floral fragrance

Because flowers contain different aromatic oils, we can smell different floral fragrances. For example, flowers such as roses and jasmine have a stronger smell. That is because the aromatic oils in these flowers evaporate to a greater extent, and we are far apart. You can also smell it; the smell of osmanthus and tuberose is relatively light, because the aromatic oil in their flowers does not volatilize very well, so their smell is relatively light. Some flowers do not contain aromatic oils, such as gypsophila, whose flowers have no smell because they do not contain aromatic oils.

3. Other ways of distributing floral fragrance

< p>Some flowers do not contain aromatic oils, but they still smell fragrant. Why is this? Because although the plant does not contain aromatic oil, it produces aromatic oil during its metabolism, so these flowers that do not contain aromatic oil can also emit floral fragrance.

Another possibility is that these flowers contain glycosides. The glycosides themselves have no fragrance, but after being decomposed by enzymes, they will emit fragrance, so these flowers can also have fragrance. Floral fragrance, such as crabapple flowers, has a floral fragrance because it contains glycosides. The smell of flowers is not necessarily fragrant. There are also many flowers that are smelly. For example, Rafflesia flowers attract insects by emitting their smell and help them spread pollen.
