Nothing will incline the German to plant this poisonous, though pretty shrub (8)
I believe the answer is:
oleander
'plant this poisonous though pretty shrub' is the definition.
'oleander' can be an answer for 'plant' (I've seen this before). I'm not certain of the 'this poisonous though pretty shrub' bit.
'nothing will incline the german' is the wordplay.
'nothing' becomes 'o' (looks like zero - 0).
'will' is a charade indicator (letters next to each other) (I've seen this in other clues).
'incline' becomes 'lean' (synonyms).
'the german' becomes 'der' ('the' in German).
'o'+'lean'+'der'='OLEANDER'
'to' is the link.
Can you help me to learn more?
(Other definitions for oleander that I've seen before include "No leader, oddly, for the flowering shrub" , "Flowering shrub from olden era, oddly" , "poisonous plant" , "tree" , "bloomer" .)
