Platycodon grandiflorus

Balloon flower gets its common name from the unopened flower buds which resemble hot air balloons. Children love to grow this plant for the balloon-like buds which pop when squeezed. The name "Platycodon" means "flat bell", which aptly describes the opened flowers.

It grows best in full sun to partial shade and well-drained, slightly acidic soil.  An easy plant to grow from seed.  Division and transplanting are difficult due to the fragile fleshy root system; however, if needed, division should be done in spring.  Deadheading will prolong the bloom season.
