Amateur European rose in several bands? (7)
I believe the answer is:
layered
'in several bands?' is the definition.
(in several layers or bands)
'amateur european rose' is the wordplay.
'amateur' becomes 'lay' (similar in meaning).
'european' becomes 'E' (abbreviation e.g. EU).
'rose' becomes 'red' (shade of red).
'lay'+'e'+'red'='LAYERED'
(Other definitions for layered that I've seen before include "Type of cake perhaps" , "Tiered" , "Made of several sheets" , "Arranged in strata" , "Stratified" .)
