Balloon flower (Platycodon grandiflorus) is one of those fun plants 
to grow in the garden with kids. Balloon flowers get their name from 
the unopened buds, which swell up prior to opening and resemble little 
hot-air balloons. Kids are fascinated by these plants and will typically 
pop them for sport by squeezing the sides, making them burst open with a 
soft, popping sound. Growing balloon flowers with children can be quite fun. 
The opened flowers resemble those of bellflowers, their kissing cousin. 
While most often deep blue or purple, white and pink varieties are also 
available. Depending on where you are, the balloon flower may also be known 
as Chinese or Japanese bellflower. Growing Balloon Flowers The balloon plant 
is easy to grow and hardy in USDA Zones 3 through 8. It will thrive in sun or 
partial shade. It likes well-drained, slightly acidic soil; and although the 
balloon flower plant will tolerate dry conditions, it prefers (and needs) 
plenty of moisture. This cold hardy plant also prefers cooler conditions in 
summer, so afternoon shade is a good idea for warmer regions. Seeds can be 
directly sown in the garden or started indoors in early spring. It is not 
necessary to cover seeds; simply moisten the area and within a couple weeks 
you should have sprouts. Thin these to about a foot (31 cm.) apart. Generally, 
balloon flowers bloom within the same season they are sown. Caring for a Balloon 
Plant Not only are they easy to grow, but these plants are easy to care for as 
well. If desired, they can be fertilized with a slow-release fertilizer in 
spring. From there, you simply water as needed.

Culture
Best grown in light, medium moisture, organically rich, well-drained loams 
in full sun to part shade. Avoid wet or poorly-drained soils. Plants are 
easily grown from seed. Division and transplanting are possible but tricky 
because of the fragile, fleshy root systems of these plants, and it is 
probably best to leave plants undisturbed once established. Deadheading spent 
flowers generally prolongs the bloom period. New season plant stems emerge 
late in spring, so gardeners must be careful not to damage crowns by early 
cultivation (leaving old plant stems in place throughout winter to the point 
when the new growth first appears helps mark plant locations). Taller plants 
often need to be staked because of floppy stems. Consider cutting back plant 
stems by 1/2 in May to reduce plant height and possibly avoid staking.
 
Noteworthy Characteristics
Platycodon grandiflorus, commonly called balloon flower, is a clump-forming 
perennial that is so named because its flower buds puff up like balloons before 
bursting open into outward-to-upward-facing, bell-shaped flowers with five pointed 
lobes. Plants are native to slopes and meadows in China, Japan, Korea and Siberia. 
Purple-blue flowers (to 2-3” across) bloom throughout summer, singly or in small clusters, atop stems typically growing to 30” tall. Ovate to lance-shaped, toothed, 
blue-green leaves (to 2” long).
 
Problems
No serious insect or disease problems. Root rot may occur in overly moist soils. Watch for slugs and snails.
 
Uses
Rock gardens or border fronts. Containers. Edging.
