Special-looking bladder cherry’s modest white flowers develop in the autumn into a juicy, cherry-like berry. At the same time the calyx begins to expand and eventually forms a loose orangey red hood with the ripe red berry shining reddish in the middle, like a paper lantern with a red light shining inside!

Bladder cherry is grown in Finland as an ornamental, and now and again it escapes in the most temperate parts of the south-west coast. It has been used in folk medicine especially in the treatment of kidney and bladder stones. This belief was according to the doctrine of signs, which held that a plant’s healing properties were reflected in its outward appearance. Bladder cherry’s fruit resembles the urinary bladder, at least from a distance, but it has no medicinal effect, although it would probably do no harm. They should not be carelessly recommended to anyone however as the raw berries contain small amounts of poisonous solanine. This is not much of a problem, however, as the berries taste sour, bitter or even totally objectionable.
