Bladder campion is native to a wide expanse in Europe and parts of Asia and Africa. It has found its way to various other regions across the globe where it is now established. Notably, bladder campion has been introduced to the Americas, Northern Europe, and Australia, where it is often found in disturbed soils. Today, bladder campion has a foothold in continents from the Southern Hemisphere to the Northern Hemisphere and is also cultivated beyond its native range.

Bladder campion hails from Europe and parts of Asia, becoming common as they found their way across the globe. This plant can be considered a weed due to their hardy natures, quick reproductive cycle, and expansive spread. Its tendency to rapidly reproduce and spread makes it an aggressive competitor for resources and space, which can stifle the growth of other, less robust vegetation in gardens and farms. Additionally, its abundant growth can result in unsightly clusters, overshadowing the aesthetics of the garden it infests. Look for its distinctive white flowers and inflated calyx to identify it. Bear in mind, its harmfulness lies not in being toxic or hazardous to humans, but in its ability to outcompete other plants. Bladder campion primarily spreads through the dispersal of its seeds, which are carried by wind and wildlife, meaning one plant can quickly become many over a short period.

The best season to remove or restrict bladder campion is in the early spring before it flowers and sets seed. It's crucial to manage this plant before it reaches the seeding stage to prevent spread.
