How does peach blossom smell?

In fact, the fragrance of flowers comes from a kind of oil cells in petals, which constantly secrete aromatic oil with fragrance. Because aromatic oil is easy to volatilize, when flowers are in full bloom, aromatic oil will be emitted with water, which is the flower fragrance that people smell! Because all kinds of flowers contain different aromatic oils, they emit different fragrances, some are rich and some are elegant. There are also some flowers in nature. Although there are no oil cells in their petals, they smell delicious. It turns out that their cells contain a substance called "glycoside", which will produce fragrance after being decomposed by enzymes.

Generally speaking, when the weather is clear and the temperature rises, the aromatic oil in the petals will evaporate faster and float farther, so the fragrance will be stronger. However, some flowers, such as cordate telosma, Milan and other flowers that bloom at night, are purer and stronger at night than during the day because of the higher air temperature, larger stomata of petals and more volatile aromatic oil.
