Plant for all to see in sheds (6)
I believe the answer is:
poplar
'plant' is the definition.
(poplar matches up with the definition plant)
'for all to see in sheds' is the wordplay.
'for all' becomes 'U' (Universal film certificate - suitable for all).
'to see in' becomes 'popular' ('in' can mean popular or trendy).
'sheds' is a deletion indicator.
'popular' with 'u' taken away is 'POPLAR'.
(Other definitions for poplar that I've seen before include "part of London" , "Tree with light, soft wood and catkins" , "part of our capital" , "Deciduous tree" , "Tree, maybe from Lombardy" .)
