The term PERFECT GARDEN can be broken down into two crossword solutions: EDEN (4 letters) and PERFECT (7 letters). EDEN is a reference to the biblical Garden of EDEN, which was described as a PERFECT paradise. PERFECT is an adjective that means 'having all the required or desirable elements, qualities, or characteristics; as good as it is possible to be.' Together, these two words describe a PERFECT garden, one that is as close to the Garden of EDEN as possible.
