Just what exactly is a Scarlet Pimpernel?

Nothing more than a humble wayside flower. Rather common, in point of fact!

According to the Webster's Dictionary, a scarlet pimpernel is:

1 : a common pimpernel (Anagallis arvensis) having scarlet, white, or purplish flowers that close in cloudy weather

2 [Scarlet Pimpernel, assumed name of the hero of The Scarlet Pimpernel (1905), novel by Baroness Orczy] :
a person who rescues others from mortal danger by smuggling them across a border
