Bud abortion means the flower buds wither before they bloom. This phenomenon may be caused by deficiencies in bud-stage management techniques or inadequate care for the flower buds; the buds wither or rot before reaching bloom time. The main causes of bud abortion are dry air and excessively high temperatures. Both Cymbidium goeringii and Cymbidium faberi require 1 to 2 months at around 5°C of low...
The varieties of Cymbidium goeringii from different regions do indeed have some minor differences. Jiangsu and Zhejiang Cymbidium goeringii generally have more tender petal colors, with more buds sheaths bearing purple veins; Hubei, Henan, Shaanxi and Anhui Cymbidium goeringii are the same, mainly with deeper petal colors and more white bud sheaths; Sichuan, Guizhou and Yunnan Cymbidium goeringii come in two types, one with thinner petals and even thinner bud sheaths, and the other with thick petals known as douban. Among these four types of Cymbidium goeringii, the thin-petaled Cymbidium goeringii from Yunnan, Guizhou and Sichuan is the most fragrant and mellow, without any off-odor; next comes Jiangsu and Zhejiang Cymbidium goeringii; Hubei, Henan and Shaanxi have slightly inferior fragrance. Anhui Cymbidium goeringii and the more southern Hubei Cymbidium goeringii differ little in fragrance from Jiangsu and Zhejiang Cymbidium goeringii, and some are also very fragrant, but overall the fragrance is slightly lighter than that of Jiangsu and Zhejiang Cymbidium goeringii. Among the fragrant-flowered Cymbidium goeringii of Jiangsu, Zhejiang, Anhui and Hubei, sometimes a somewhat pungent off-odor appears in the fragrance. Whether Anhui and Hubei Cymbidium goeringii are fragrant is also related to temperature and moisture during the flowering period; the flowering-period temperatures here are lower, which is not conducive to the volatilization of aromatic oils, so it is not entirely a problem of the Cymbidium goeringii itself. Douban Cymbidium goeringii is generally not fragrant. Cymbidium goeringii in southwestern Hubei, namely the Enshi region, belongs to the same strain as that of Yunnan, Guizhou and Sichuan, and is very fragrant and mellow.

The fragrance of orchids comes from the anther cap, that is, the pollinia on the nose. From this it can be inferred: those with male-ized pollinia will be more fragrant; Further inferred: those whose column splits into many small columns will be more fragrant, such as Yu Hudie. 

In addition, fragrance is related to region and orchid species: Cymbidium goeringii from the Zhejiang area is very fragrant; Cymbidium goeringii from many places in Henan and Hubei has a light fragrance or no fragrance; Cymbidium faberi is mostly fragrant, but its fragrance is far less delicate and pleasant than that of Cymbidium goeringii; Orchid species such as Cymbidium tortisepalum and Cymbidium tortisepalum var. longibracteatum generally have less fragrance than Cymbidium goeringii.
