Lesson Summary. Robert Frost's 1923 poem 'Nothing Gold Can Stay' explores the idea that nothing good or precious can last forever by using nature and The Garden of Eden as metaphors for cycles of life and death and the loss of innocence.elow is the full text of the poem for your reference: Nature's first green is gold, Her hardest hue to hold. Her early leaf's a flower; But only so an hour. Then leaf subsides to leaf. So Eden sank to grief, So dawn goes down to day, Nothing gold can stay.
