I cannot claim much knowledge of Ella Young beyond her Wikipedia article, nor have I studied this poem. But it seems to speak of a little bit of myth, something magical and beautiful, and I like it.
The Rose of Silence
By Ella Young (1867 – 1956)
In a green stillness hidden from sun and moon
Under the sea,
A blossom swings by the High-Queen’s doon.*
On a silver tree;
And every poet has dreamed since time begun
Of that hidden place,
But only those who have said farewell to the sun
May come to the doon by the silver tree
Or find in hollow or height,
Under the still green tideless sea
The Rose of Silence and Night.
