Rose needs cad to reform (8)
I believe the answer is:
ascended
'rose' is the definition.
('ascend' can be a synonym of 'rise')
'needs cad to reform' is the wordplay.
'to reform' is an anagram indicator (letters in a new form).
'needs'+'cad'='needscad'
'needscad' anagrammed gives 'ASCENDED'.
(Other definitions for ascended that I've seen before include "Climbed, went up" , "R [ROSE]" .)
