Juliet has a car and a flowering tree (9)
I believe the answer is:
jacaranda
'tree' is the definition.
(jacaranda is a kind of tree)
'juliet has a car and a flowering' is the wordplay.
'juliet' becomes 'J' (phonetic alphabet: alpha, bravo, charlie etc.).
'has' says to put letters next to each other.
'flowering' indicates an anagram (letters develop or 'flower' into another form).
'a'+'car'+'and'+'a'='acaranda'
'j' put after 'acaranda' is 'acarandaj'.
'acarandaj' is an anagram of 'JACARANDA'.
(Other definitions for jacaranda that I've seen before include "exotic wood" , "Tropical flowering tree" , "Tropical American tree" , "Tree common in Pretoria, South Africa" , "Tropical tree with fern-like leaves" .)
