When I Neptune wear my Naught less

When I Neptune wear my Naught less—crown
Twisting floridly like a narwhal up and down!
My mercury flower a bouquet sea-cucumber
Wasp-castanet-stars of pollen, endless in number
Biblical in Eden’s darkness is her rose pearl seed,
Sunsets burning; inimitably withering like a weed.
“I” is the initial letter of this her oceans—me?
“O” is for that blissful bloom the oblivion of—we!
