Alpine perennial plant (9)
I believe the answer is:
edelweiss
'alpine perennial plant' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for edelweiss that I've seen before include "Swedes lie about small white flower in Switzerland" , "high growth" , "Perennial Alpine plant -- we see lids (anag)" , "flower as national symbol" , "Ewe slides on the alpine plant" .)
