A flower came up (5)

I think it could be either:

Which length description are you looking for?:

arose

'came up' is the definition.
(I've seen this before)

'a flower' is the wordplay.
'flower' becomes 'rose' (I've seen this in other clues).
'a'+'rose'='AROSE'

(Other definitions for arose that I've seen before include "Got out of bed" , "Came about" , "Issued" , "stemmed" , "Emerged from" .)

I've seen this clue in the Evening Standard, The Telegraph and The Globe and Mail.
