The Scarlet ..., Sir Percy Blakeney (9)

I believe the answer is:

pimpernel

(Other definitions for pimpernel that I've seen before include "(Scarlet) plant of the primrose family" , "The Scarlet - (Orczy)" , "rarely identified in France" , "Baroness Orczy's scarlet flower?" , "Target for revolutionary French" .)

I've seen this clue in the Irish Times (Simplex) and The Irish Times.
