Convolvulus

A long long time ago, a heavy wagon was stuck in the mud and the wagon driver was unable to free it. Just then, by sheer chance, the Madonna passed by.

'I am thirsty,' she said. 'Give me a drink and I will set your wagon free.'

'Willingly,' said the man, offering her the bottle, 'but I don't have a cup.'

'I can provide the cup,' said the Madonna. And she broke off a white flower, with red stripes, in the shape of a chalice and she used it to drink from.

Ever since then, people have called the flower of the convolvulus, 'The Madonna's Cup.'
