In "Nothing Gold Can Stay,"  Robert Frost alludes to Eden because B. Eden's short-lived perfection is similar to the temporary perfection of nature;s first green.
Eden, of the Heaven, was perfect until Eve tried the apple that the snake told her to and was thus expelled from Eden along with Adam. Thus, Heaven was no longer pure and pristine as it used to be.
