eden

I'm a little stuck... Click here to teach me more about this clue!

'garden' is the definition.
(I've seen this before)

I don't understand how the remainder of the clue works.

(Other definitions for eden that I've seen before include "Early garden - Cornish project" , "The - - Project, Cornwall" , "The perfect garden in need" , "PM 1955-56" , "Badly need the garden" .)

I've seen this clue in The Guardian.
