Platycodon grandiflorus is a species of perennial flowering plant of the family Campanulaceae and the only member of the genus Platycodon (from Greek "πλατυκώδων", meaning 'a broad bell'). This species is known as platycodon or Chinese bellflower. Depending upon the region, it is also referred to as the Japanese bellflower, common balloon flower, or balloon flower. It is native to East Asia (such as China, Korea, Japan, and East Siberia) and bears big blue flowers, although varieties with white and pink flowers are in cultivation. In Korea, white flowers are more common.
The root of this species (radix platycodi) is used extensively as an anti-inflammatory in the treatment of coughs and colds; in Korea the plant is known as doraji (도라지) and its root, either dried or fresh, is a popular ingredient in salads and traditional cuisine. However, doraji (Chinese bellflower) should not be confused with Korean bellflower. Chinese bellflower (called 桔梗 in Chinese) is used in traditional Chinese medicine.
The plant is also a popular garden ornamental. It is hardy to USDA plant hardiness zone 3 and requires little care.
