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