Bladder Campion is a perennial wildflower found in dry scrubby environments, preferring sun, unlike Red Campion. It can grow to about 1m tall, branching and is more common in the south than north. White flowers open in mid-summer and behind each flower is an inflated, papery bladder, usually pale creamy-green and very conspicuous. White petals are divided into 2 lobes. The leaves are edible. The whole plant dies down in winter, to re-emerge in spring. Useful on dry, sunny, open field margins.
