European out sees wild plant (9)
I believe the answer is:
edelweiss
'plant' is the definition.
(edelweiss is a kind of plant)
'european out sees wild' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'out' indicates an anagram.
'sees'+'wild'='seeswild'
'seeswild' with letters rearranged gives 'delweiss'.
'e'+'delweiss'='EDELWEISS'
(Other definitions for edelweiss that I've seen before include "Ewe slides on the alpine plant" , "Swedes lie about small white flower in Switzerland" , "White-flowered alpine plant" , "flower as national symbol" , "high growth" .)
