Called into London park with a climber (9)
I believe the answer is:
hydrangea
'climber' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Maybe there's an association between them I don't understand?
'called into london park with a' is the wordplay.
'called' becomes 'rang' ('ring' can be a synonym of 'call'**).
'into' indicates putting letters inside.
'london park' becomes 'hyde' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'rang' put into 'hyde' is 'hydrange'.
'hydrange'+'a'='HYDRANGEA'
Can you help me to learn more?
(Other definitions for hydrangea that I've seen before include "Ornamental flowering shrub - handy gear (anag)" , "Common garden plant" , "Shrubby plant with showy flowers" , "Shrub of the saxifrage family -- angry head (anag)" , "Flower you might find in garden hay, oddly" .)
