Pine produces this flower, cut to take home (5)
I believe the answer is:
rosin
'pine produces this' is the definition.
(resin from pine trees)
'flower cut to take home' is the wordplay.
'flower cut' becomes 'ros' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to take' says to put letters next to each other.
'home' becomes 'in' ('he's home' can mean 'he's in').
'ros'+'in'='ROSIN'
(Other definitions for rosin that I've seen before include "Wax for violin bow etc." , "Sticky stuff rubbed on violin strings" , "Colophony" , "Varnish etc. from turpentine" , "No sir; it is rubbed on violin bows" .)
