Tread in the tulips, Nice and light, Swan lake style, Add some height

I'm where the Sun goes down to sleep I inspire sailors to sail waters deep

I greet you before you speak. My tail tells truths my mouth never could. I guard your home but beg at your table. I can be fierce as a wolf or small as a shoe. What am I?

Hidden in a shell's embrace, a treasure from the deep. A moonlit drop of ocean's grace, where secrets softly sleep.

I’m green and I’m tall. Cut me down, and I’m your floor, cutting board, even your sheets!
