Biblical refugee with American flower (5)
I believe the answer is:
lotus
'flower' is the definition.
(I know that Lotus is a type of flower)
'biblical refugee with american' is the wordplay.
'biblical refugee' becomes 'lot' (I've seen this before).
'with' says to put letters next to each other.
'american' becomes 'US' (United States).
'lot'+'us'='LOTUS'
(Other definitions for lotus that I've seen before include "Plant - yoga position" , "In myth, a plant whose fruit induced forgetfulness" , "Kind of water lily" , "Mythical fruit inducing state of luxurious dreaminess" , "Indian waterlily" .)
