Red centaury and yellow bed-straw and white bladder campion flourish.
"Priscilla's Spies" by George A. Birmingham
A bladder campion (Silene inflata) is another curiosity.
"Fishes, Flowers, and Fire as Elements and Deities in the Phallic Faiths and Worship of the Ancient Religions of Greece, Babylon," by Anonymous
You will easily recognise the Common Bladder Campion by this curious calyx.
"Flowers Shown to the Children" by C. E. Smith
The campion bladders the children burst,
The bramble that clutches and won't take nay,
And the pensive delicate foxgloves nursed
In woods that curtain from glare of day.
"A Country Nosegay" by Alfred Austin
