So, a red rose! (6)
I believe the answer is:
soared
'rose' is the definition.
(soaring is a kind of rising)
'so a red' is the wordplay.
'so'+'a'+'red'='SOARED'
(Other definitions for soared that I've seen before include "Flew upwards or high in the sky" , "Rose high into the air" , "Rose high in flight like bird" .)
