Sting to anger (6)

I believe the answer is:

nettle

This clue is a double definition.

'sting' is the first definition.
(I know that nettle is a more specific form of the action sting)

'to anger' is the second definition.
(nettle can mean to irritate or anger)

(Other definitions for nettle that I've seen before include "Irritate, annoy" , "Grasp it firmly and it will not sting" , "sample of herbal tea?" , "Common stinging plant" , "Sting or annoy with the plant" .)

I've seen this clue in The Globe and Mail.
