Dandelions are homely flowers: familiar, common and well-used. They are stuck with a reputation for causing bed-wetting. The leaves are used as country cure-alls and the flowers made into country wine. In Victorian times, it was an aristocrat among winter salads, cultivated with care and eaten by the wealthy in dainty sandwiches. But fashions changed and its heyday passed. Now it has returned to its place as a lowly weed and the bane of the tidy gardener.
