Plant some privet, perhaps, or some wretched geraniums (5)
I believe the answer is:
hedge
'plant some privet perhaps' is the definition.
I can't tell whether this defines the answer.
'some wretched geraniums' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'HEDGE' is hidden in the letters of 'wretched geraniums'.
'or' is the link.
Can you help me to learn more?
(Other definitions for hedge that I've seen before include "Protect oneself from loss" , "Duck" , "Qualify by conditions; boundary of bushes" , "Barrier of shrubs or bushes" , "bush as a > barrier" .)
