Head of thyme found among fresh herbs in beds (6)
I believe the answer is:
berths
'beds' is the definition.
(berth is a kind of bed)
'head of thyme found among fresh herbs' is the wordplay.
'head of' says to take the initial letters.
'found among' indicates putting letters inside.
'fresh' is an anagram indicator.
The first letter of 'thyme' is 't'.
'herbs' is an anagram of 'berhs'.
't' placed within 'berhs' is 'BERTHS'.
'in' acts as a link.
(Other definitions for berths that I've seen before include "Bunks; moorings" , "Train or ship bunks" , "Beds on board" , "Beds on ship or train" , "Passenger beds on ships" .)
