Gorse seen regularly, like grass perhaps? (5)
I believe the answer is:
green
'like grass perhaps?' is the definition.
(I know that grass is green)
'gorse seen regularly' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'gorse'+'seen'='gorseseen'
The alternating letters of 'gorseseen' are 'GREEN'.
(Other definitions for green that I've seen before include "Grassy area; politician" , "Gullible" , "Concerned with the environment in colourful way" , "Unripe; environmentalist" , "Ecological" .)
