      Today I want to talk about a stimulating plant that is known by such flattering aliases as “Stinking Ninny” and “Mare’s Fart". It's called ragwort, and although it is a flower, it's definitely not the type you want to give your wife on Valentine's Day.

    2. A nickname for any of several other types of flowers, including the fleabane and dandelion.

      The dandelion was long popularly known as the ‘pissabed’ because of its supposed diuretic properties, and other names in everyday use included mare’s fart, [...] open arse and bum-towel. One or two of these earthy appellations may unwittingly survive in English yet.

    Andrew Lark deliberately avoided looking down at Nona, for that might suggest to her that he cared as much as a trotting mare’s fart what he thought of her fears.
