Rows of apples, perhaps having yellow edible leaves (7)
I believe the answer is:
orchard
'rows of apples perhaps' is the definition.
I know that 'apples' relates to this answer.
'yellow edible leaves' is the wordplay.
'yellow' becomes 'or' (heraldic term).
'edible leaves' becomes 'chard' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'or'+'chard'='ORCHARD'
'having' acts as a link.
Can you help me to learn more?
(Other definitions for orchard that I've seen before include "Field of fruit trees" , "Land growing 15 across" , "Plantation of fruit trees" , "Fruit-tree plot" , "Area with fruit trees" .)
