It grows in orchards (5)
I believe the answer is:
chard
'it grows' is the definition.
The definition suggests a singular noun which matches the answer.
'in orchards' is the wordplay.
'in' says the answer is hidden in the clue.
'CHARD' is hidden in the letters of 'orchards'.
Can you help me to learn more?
(Other definitions for chard that I've seen before include "Leaf stalks from a kind of beet" , "Vegetable; Somerset town" , "Green vegetable" , "Variety of beet with edible leaves" , "Kind of (Swiss?) beet with edible leaves" .)
