Bladder Campion

Bladder campion is a hairless perennial herb, with branched stems 1-3 ft tall. The plant is easily distinguished by its few large drooping white or greenish white flowers, with deeply lobed petals, and its avoid, inflated, bladder-like greenish sepal tube with a network of darker veins. Flowers are 1.5-2.5 cm across, usually in lax branched clusters. Flowering: June-August.
