Plant raised in Europe (3)
I believe the answer is:
rue
'plant' is the definition.
(type of shrub)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for rue that I've seen before include "Bitterly regret - plant" , "Regret the bitter herb" , "Plant producing oil" , "The 'herb of grace'" , "Lament; a herb" .)
