I need help choosing a name for a fantasy character...?

She's a wood faerie who's also a thief and a compulsive liar. For most of the story, she pretends to be the princess of the faerie kingdom, who was kidnapped several years before. Anyway, she needs a name, but I can't decide on one. Which do you think? (The princess's name is Mercuria, by the way, if that helps out at all.)

The list of names I've been trying to choose from:

Mahogany

Dandelion

Hawthorne

Sawyer

Mallow

Montague (Monty)

Also feel free to suggest other names. I'd like something botanical, since she's a wood faerie and all. (Yeah, I know Sawyer and Montague aren't botanical, I just like the names. XD)

Thanks in advance for the help. I'm very indecisive. :/
