Tread lightly, she is near
Under the snow,
Speak gently, she can hear
The daisies grow.
All her bright golden hair
Tarnished with rust,
She that was young and fair
Fallen to dust.
Lily-like, white as snow,
She hardly knew
She was a woman, so
Sweetly she grew.
In the first stanza , snow was already referenced once. Now it is mentioned again, though in the context of her pale complexion due to her death rather than the gloomy scenery. 
 
 Isola was compared to a  daisy in line 4  to express her innocence and purity, which lilies also famously express.  The lily  was a symbol for Hera in Greek Mythology. However, they also symbolized death, seeing that many believed that when one dies, their lost innocence is regained. 
 Lillies are generally dormant in winter, making it a possible allusion to Wilde’s belief that Isola  “is at rest”  in this snow rather than dead.
