Yahi'i was a species of plant with stalks that could be easily cut down when they were ripe. In 19 BBY, while near the Zi-Zhinn Marketplace on the Galactic Empire's capital planet of Coruscant, Jedi Master Even Piell thought that a group of Imperial stormtroopers he was fighting would cut him down like a ripe yahi'i stalk if he attempted to retreat.
Behind the scenes
The Yahi'i plant was first mentioned in Coruscant Nights I: Jedi Twilight, a 2008 novel written by Michael Reaves. On March 11, 2011, "Citadel Rescue," an episode of Star Wars: The Clone Wars, retconned Even Piell's death to occur in the episode, instead of the novel, making it ambiguous how the events of the novel fit in with the altered continuity.
