Platycodon grandiflorum, also known as Campanula, belongs to the genus Platycodon, a perennial herb. It can grow to about one and a half meters, its leaves are oval and green, and its stems are upright and not forked. Leaves and stems are hairless, and their flowering period is around September, with purple flowers and white stamens. There are six petals.
The fruit ripens around October. The fruit is green and round. Platycodon grandiflorum is mainly distributed in Jiangsu, Zhejiang, Shandong, Guangxi, Guangdong, Henan, Yunnan, Guizhou and Chongqing in China. Mainly grows in grasslands, plains, hills and other places.
I like growing up in sunny, fertile and humid land with warm climate, good drainage and ventilation, and very cold-resistant and drought-resistant. I can't plant it in waterlogged land, because growing in waterlogged land will make it wither or stop growing. People often plant them in parks, courtyards and gardens for people to watch and decorate the scenery.
