The new artistic director of Shakespeare's Globe Theatre, Emma Rice, was interviewed on the Radio 4 Today programme yesterday (listen here; scroll along to 1:41:00 approximately). One of Shakespeare's expressions she cited was chimney-sweepers, which was a Warwickshire dialect word for the dandelion. It appears in Cymbeline:
Golden lads and girls all must,
As chimney-sweepers, come to dust.
The name dandelion is a corruption of the French dent de lion, lion's tooth, so named because of the shape of the leaves. Lion's tooth is just one of the synonyms and dialect names for this flower. Others include: Irish daisy, blowball, monk's head, priest's crown, cankerwort, doon-head clock, face clock, fairy clock, four o'clock, witch gowan, milk witch and swine's snout. Other dialect names reflect the fact that the roots of the dandelion have a diuretic effect: pissabed, pee-a-bed, wet-a-bed, Jack piss-the-bed, pissy bed and tiddle bed.
