Trumpet weed

The trumpet weed was a type of large plant with cup-like ends found on the planet of Dac. Once fossilized, trumpet weeds could be polished and turned into art objects. The Quarren Tikkes, Senator of Dac around 32 BBY, once offered his colleague Palpatine of Naboo three large pearls from the seas of his homeworld, held in the ends of such fossilized trumpet weeds. The Naboo senator subsequently displayed them in his apartment suite as a part of his collection of historic art and artifacts.
