Balloon flowers (Platycodon grandiflorus) are clump-forming perennials in the bellflower family (Campanula). They are hardy in Zones 3-8 and prefer full sun to part shade. As the plant grows, the buds swell like small balloons before emerging as upward-facing star-shaped flowers with 5 petals.
Balloon flowers usually grow about 0.5 m. The leaves are lanceolate and green with a blueish shade. They bloom in summer with multiple flowers from each stem.
We can propagate them from seed or buy them in a nursery. Once established, they are harder to move because of a long taproot. They are low-maintenance, reliable, and long-lived, a valuable addition to a home garden.
