Bladder Campion

Silene vulgaris

This pretty flower is named after the inflated bladder-like sac behind the petals. Growing between 60cm and 1m tall this white wildflower is also known as ‘Maidens Tears’, ‘Cowbell’, and ‘Common Bladder Catchfly’ even though it doesn’t technically catch flies!

How to spot it

Bladder Campion is a perennial wildflower with a green bladder-like calyx with purple veins make it easily identifiable. The ragged looking white flowers, which grow at the end of the bladder, have five two-lobed petals and are roughly 2cm wide with long protruding stamens. It is said they have an aroma similar to that of cloves. Many flower heads can be found on one medium height plant. Its stalkless bluish-green leaves are long and thin on mature plants.

Where to spot it

It is fairly common in Britain, but is mostly found in the south of England in meadows and fields, and along roadside verges, dry banks, and hedgerows.

Things you might not know

  • The young leaves are sometimes added to salads in the Mediterranean where it grows much more abundantly.
  • During the summer months, Bladder Campion can often found covered in ‘Cuckoo Spit’ as this is a favourite food-plant of the Froghopper. The early English botanist John Gerard called it ‘Spatling Poppie’ for this very reason.
  • In Roman mythology the Goddess Minerva turned the young boy Campion into this plant after he fell asleep instead of catching flies for her owls. The bladder represents the bag he should have filled.
