The delicate fragrance of orchids is astonishing and intoxicating. It is known as the "ancestral fragrance" and "the best fragrance in the world". People compare it to a gentleman, as a symbol of nobility and elegance. Moreover, it has always been called "Lan Zhang" to describe the beauty of poetry and prose, and "Lan Jiao" to describe the true friendship.

Orchidaceae is one of the largest "families" in plant taxonomy, with many species. Some scholars have spent their whole lives struggling to distinguish them clearly. But roughly speaking, the orchids we often refer to are flowers in the genus Orchid, which often grow among rocks and grass on hillside. There are two main types of them: those that live on the ground and those that grow epiphytically. Most of our common orchids are terrestrial. Ground-growing orchids can be divided into spring orchids, summer orchids (also known as nine-section orchids), autumn orchids and winter orchids according to their blooming seasons.

The structure of orchids is different from ordinary flowers. Normal flowers are divided into sepals and petals; the sepals and petals of orchids are indistinguishable and are collectively called perianth. The perianth is composed of six petals, divided into two inner and outer whorls, each with three petals.

my country has cultivated orchids for more than 2,000 years, and there are records of orchid planting and orchid chanting in the past dynasties. In recent years, with the development of gardening, more extensive introduction, cultivation and research of orchids have been carried out across the country, and orchid exhibitions have been held frequently. Chinese orchids continue to spread abroad, winning high praise from international friends.

In addition to being ornamental, the flowers, leaves, fruits, and roots of orchids can also be used as medicines, with the functions of clearing away heat and detoxifying, resolving phlegm and relieving cough, and stopping bleeding and analgesia.
