10 Different Types of Balloon Flowers

A purple balloon flower blooming in the garden

Balloon flowers belong to genus ‘Platycodon,’ and they are one of a kind: Unlike so many other genera of flower families, this one only has one species under its belt, the Platycodon grandiflorus. Despite being a single species, cultivars of balloon flowers are made to tweak their color and design to add to its aesthetic.

These beautiful, colorful, very useful flowers are also called Chinese bellflowers, and they belong to the bellflower family Campanulaceae native to East Asian countries, including China, Korea, and Japan. The flower is commonly termed the balloon flower because of its balloon-like bud structure.

For their simple five-pointed inflorescence, these flowers are a favorite as garden ornaments and are often found blooming in parks and flower beds. Although they are usually purple, they are often mixed with other species to produce several cultivars that can range from pink to white and blue. Even the simple star-like petal pattern can be changed into a complex ten-petal one producing ‘double’ varieties.

In its native lands, it is grown extensively for its famed medicinal properties that are said to treat respiratory diseases. Have a look at all the different cultivars that can be derived from the single bellflower species.

The flowers have five lobes that have a thick rubbery texture and are arranged in the shape of a star around another star-shaped filament arrangement. The seeds occur in a seed pot with five valves that open from the head, and the leaves are unstalked, becoming narrower as they proceed upwards. These plants form clumps on the ground, so they can also serve well as ground cover in flower beds. It is a perennial plant that can live for years on end.

In Art and Cultures

In Europe, it is said that the five points represent the five senses, and Greek philosophers deemed them a symbol for the five elements of the earth. In Japan, the flower appears as a symbol on the coat of arms of members from important families, while practitioners of Wiccan witchcraft see a pentagram in the flower and use it in rituals. The simple beauty of the flower makes it charming for every culture.

Doraji taryeong, a song derived from the locally found flower, is one of the most popular folk songs in both North and South Korea. It is also sung in China among the Korean descendants. Another song by the same name is known as Toraji in Japan.

The folk song originally came from the Hwanghae Province. However, the version currently sung is considered to be from the Gyeonggi Province since the rhythm and melody have tweaked to acquire different characteristics.

In popular culture, Platycodon is a symbol of friendship, and it can also symbolize eternal love and purity of spirit.

Growing Platycodon Plants

The balloon flower plant

If you plan on growing these fun flowers in your garden, the seeds need to be directly sown in the soil during the early spring months. The seeds may or may not be kept covered; you need only dampen the area of plantation, and within a couple of weeks, a sprout will be visible. You should spread them out to about a foot apart, and if you are lucky, you should have flowers greeting you within the season.

To grow well, balloon flowers need plenty of light, but can grow sufficiently well in partial shade. The soil requirements are not many, but a slightly acidic soil is preferred. The plants will not need too much watering and can even manage short periods of drought.

Along with the ease with which they grow, the plants are easy to cater to and require minimal upkeep. If a mild fertilizer is added at the beginning of the season, only regular watering will be needed for them to thrive throughout. Sit back, and enjoy your plant slowly flower and blossom before summer is over.
