Something you put in your mouth, and a type of tree. Add a word to the end, you get footwear. Add a letter instead, it's part of your mouth. Reversed, it can contain a liquid.

I can be drawn without ink, I can be shed without fur. Built by bone, or from birth you've known. We've bonds of iron so keep me close to your heart, for death might loom, should we part.

I never bloom, yet green I stay, with frilly leaves that softly sway. In shady spots I love to grow, a woodland friend you’ve come to know. No flowers here, but don’t you spurn, I’m leafy, lush I am a?

I can spin without turning, paving roads only I take. Many eyes discerning, a kiss and you won't wake

A woman's name, a colour, a tree and a cocktail ingredient. Reversed, it is a bad letter of the Alphabet.
