Plant's strange allure (6)
I believe the answer is:
laurel
'plant's' is the definition.
The answer is an example.
'strange allure' is the wordplay.
'strange' indicates an anagram.
'allure' is an anagram of 'LAUREL'.
(Other definitions for laurel that I've seen before include "Shrub with glossy leaves" , "Hardy's comic pal" , "Honours" , "Stan possibly" , "Companion to Hardy" .)
