Floral emblem of the House of York (5,4)

I believe the answer is:

white rose

(Other definitions for white rose that I've seen before include "Emblem of York" , "Yorkshire emblem" , "Otherwise (anag) - Yorkshire's emblem" , "Pale fragrant blossom - may be otherwise" .)

I've seen this clue in The Times.
