I believe the answer is:

rose

I'm a little stuck... Click here to teach me more about this clue!

'stood up' is the definition.
(I've seen this in another clue)

'for england' is the wordplay.
'for' becomes 'ros' (I can't justify this - if you can you should believe this answer much more).
'england' becomes 'e'.
'ros'+'e'='ROSE'

Can you help me to learn more?

(Other definitions for rose that I've seen before include "was being promoted" , "beauty" , "Gained height" , "Prickly bush" , "Herb - girl's name(s)" .)

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