Flora's Crown is an object that plays a minor role in the eleventh Dark Parables game, Swan Princess and the Dire Tree.
The crown appears to be a bright gold-colored metal in the shape of roses, flowers, and other plant forms so it looks like a wreath.
Interestingly, when she's shrunken into Thumbelina, Flora's crown changes into a small wreath of twigs instead of flowers. It's possible the crown only has limited power on its own, which are most likely gained from being near Flora, and not being the source of her powers.
The crown seems to grant unstable power over nature to its wearer. Elise is shown to become merged with nature itself when she wears the crown, and has to undergo a transformation before she can even use the powers. The crown also appears to affect one's mental health and possibly amplify obsession. The only wearer that can deal with these effects is Flora, who is always shown in a state of calm.
