What are the reasons a wild-collected Songchun orchid does not have fragrant flowers after being brought down the mountain

The orchid Songchun is a variety of Cymbidium faberi (Huilan), and most varieties of Cymbidium faberi are fragrant. If your wild-collected Songchun orchid is not fragrant, the first thing to consider is the issue of this orchid's place of origin and variety. This is because orchids produced in many orchid-growing regions have no fragrance, and may even have a strange odor. This is the variety issue of the orchid's place of origin; this variety of orchid itself is just.
In addition, Cymbidium faberi orchids all rather prefer light, and Songchun, this variety of Cymbidium faberi, is very similar to Cymbidium faberi in many ways, including its requirements for light and humidity.
In daily care, if the Songchun orchid is placed in a relatively shady spot for a long time, especially during the flowering period, and never gets suitable light, its flowers will very likely lack some fragrance, or even have no fragrance at all. Therefore, in daily care, Cymbidium faberi orchids, especially during the flowering period, should be given more scattered light; letting the plant and its flowers bask in the sun often will greatly enhance the fragrance of the flowers.
In fact, it is not only the flowers of Cymbidium faberi and Songchun that are like this; the flowers of Cymbidium goeringii (Chunlan), Cymbidium ensifolium (Jianlan), Cymbidium sinense (Molan) and other orchids are the same. In an environment with a bit more ample scattered light, their fragrance will be greatly enhanced.
