Old newspaper article about name for plant (8)
I believe the answer is:
oleander
'plant' is the definition.
(oleander is a kind of plant)
'old newspaper article about name' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'newspaper article' becomes 'leader' (I've seen this before**).
'about' is an insertion indicator.
'name' becomes 'n' (common abbreviation e.g. on forms).
'leader' going around 'n' is 'leander'.
'o'+'leander'='OLEANDER'
'for' is the link.
(Other definitions for oleander that I've seen before include "Adore Len (anag.)" , "Mediterranean shrub" , "Evergreen flowering shrub from olden era" , "Reloaned for evergreen shrub with bright flowers" , "bloomer" .)
