Motel site sporting evergreen shrub (9)
I believe the answer is:
mistletoe
'evergreen shrub' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'motel site sporting' is the wordplay.
'sporting' indicates anagramming the letters.
'motel'+'site'='motelsite'
'motelsite' with letters rearranged gives 'MISTLETOE'.
Can you help me to learn more?
(Other definitions for mistletoe that I've seen before include "Kissed-under plant" , "put up for a Christmas function?" , "Viscum album, much sought-after around Christmas" , "Evergreen plant" , "Valley of the -, best seller by Jacqueline Susann" .)
