Balloon flower (Platycodon Grandiflorus) is a clump-forming perennial flower, a member of the easy-to-grow bellflower family of plants. They are so named because puffy, balloon-like buds swell up to produce the 2- to 3-inch star-shaped flowers. Blooming all summer long, it is an excellent plant for border gardens or rock gardens, and it freely self-seeds in the garden. The species plant has intense blue-violet flowers, but there are also cultivars with white and pink blooms. Balloon flower is generally planted in the spring after the danger of frost has passed. It grows quickly to bloom in its first year.

Balloon Flower Native Habits
The plant has a clump-forming growth with alternate bright green leaves that form along the tall stems. Balloon flower
will grow to about 1 – 2 1/2 ft. tall, by about a foot. to 18 inches wide. Dwarf varieties won’t grow much taller than 1 foot high.
How to Grow and Care for Balloon Flower
Overall, balloon flowers
are fairly low-maintenance plants and are quite pest- and disease-resistant. You can start with nursery plants or grow your balloon flowers from seed. Planted in the early spring after the threat of frost has passed, balloon flowers should bloom during their first season. However, you also can plant them later in the growing season (spring to fall), though you might not get blooms until their second year.
Balloon Flower Lighting
You will get the most flowers if you plant balloon flowers
in full sun (at least six hours of sunlight on most days). However, they will be fine in part shade and might actually prefer some shade from where the afternoon sun is especially hot.
Balloon Flower Soil Care
Balloon flowers prefer organically rich, loamy soil that has good drainage. They don’t grow well in dense soil, such as clay. They like a soil pH in the 5.5 to 7.5 range.
Balloon Flower Watering
Keep the soil of young plants consistently moist but not soggy. Once established, balloon flowers like a moderate amount of moisture in the soil, but they can tolerate short periods of drought. They won’t need a lot of supplemental watering unless you have a long period without rainfall that causes the soil to dry out.
Balloon Flower Temperature & Humidity Care
Balloon flowers are hardy and do well in USDA growing zones 3 to 8. Their ideal temperature range is between 60 and 80 degrees Fahrenheit, but they can withstand higher temperatures if they have some shade in the afternoon. Frost can kill young plants and will cause established plants to die back into the ground in the fall. Balloon flowers tolerate both humid and dry air conditions, provided they have the right amount of soil moisture.
Balloon Flower Fertilizer
Balloon flowers typically don't need supplemental feeding if you have rich soil. But a layer of compost in the fall can help them replenish the energy they expend blooming during the growing season. If you have poor soil, use an all-purpose, slow-release fertilizer in early spring.

Balloon Flower Common Pests/Diseases

Slugs and snails may prove to be a problem for your balloon plant, especially in moist conditions. To deter these pests, try setting out a bowl of cheap beer. The gastropods will be attracted to the fermented beverage, causing them to fall in and drown. Also, if soil drainage is inadequate, your plant may develop root rot. Excessive moisture can also damage the foliage; be sure to prune leaves when necessary to increase air circulation throughout the plant.
