This cultivar inherits the fine qualities of its parents and has green and thick petals and sepals from C. serratum and the aromatic scent from C. goeringii. The inflorescence is upright，with 1 flower，12–18 cm in length. The petals are ovate，light-green with a dark-green midrib，1.5–2.5 cm in average vertical diameter and 0.8–1.2 cm in transverse diameter. The lip is white or pink with purple-red markings，its average length is 1.5–2.5 cm. The column is yellow-greenish. The flowering period is in late December to the middle to late January next year and lasts for about one month. This cultivar is characterized by strong growth vigor with a lengthy period of flowering and high ornamental value，which gives the broad prospects of commercial application.
