Baubles, bangles, and berries
Poor Pollia condensata.
Some tropical plants attract animals with their smell or taste so that animals will eat them and poop their seeds far and wide.
This plant's berries, however, have no nutritional value, so it had to evolve a more deceptive method.
It's unique metallic blue berries are intensely reflective, more so than any other living thing on earth.
That's how it tricks birds into taking them. Birds can't resist plucking off the berries and flying them back to their nests.
That's where they use the berries as decoration.
