Chameleon rose

A chameleon rose was a flower that changed color with the mood of its owner.

In 2364, Wyatt Miller gave Deanna Troi a chameleon rose as a gift. The rose had golden leaves and a golden stem. It was blue when Miller held it and turned red, then white when Troi held it. It later turned purple while still in Troi's hands.
