Crystal bush

Crystal bushes were crystalline structures found on the surface of the planet Garasu. They came in the colors blue, pink, and yellow. The crystal bushes had the ability to reflect light, which could impact the vision of humans and B1-series battle droids. This property was utilized by the clone shock trooper Lock Down during a blasterfight with battle droids, an event that took place during the Clone Wars sometime between 20 BBY and 19 BBY. The clone broke off a shard from a crystal bush, and directed the light to shine into the photoreceptor of a B1 battle droid, blinding it. Lock Down then tackled the droid into another bush, sending tiny, sparkling shards into the air.
