Taken from wikipedia's page at:

"Platycodon grandiflorus is a species of herbaceous flowering perennial plant of the family Campanulaceae, and the only member of its genus. It is native to East Asia (China, Korea, Japan and East Siberia). 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 (referring to the balloon-shaped flower buds).

Growing to 60 cm (24 in) tall by 30 cm (12 in) wide, it is an herbaceous perennial with dark green leaves and blue flowers in late summer. A notable feature of the plant is the flower bud which swells like a balloon before fully opening.[1] The five petals are fused together into a bell shape at the base, like its relatives, the campanulas. There are varieties with white, pink and purple blooms in cultivation.[2] In Korea, white flowers are more common. This plant[3] together with its cultivars 'Apoyama group'[4] and 'Mariesii'[5] have gained the Royal Horticultural Society's Award of Garden Merit."
