Murakami orchid
The Murakami orchid, also known simply as a black orchid, was a species of plant from the Murakam system.
The plant was Force-sensitive and had a high midi-chlorian count. It was said to bond only with people whose midi-chlorian concentration was similar, and could "speak" with the bonded person (usually a Jedi) through telepathy. The bonded Jedi had to remain near it for the plant to survive, and during the time of the Old Republic, the Jedi kept these flowers in an incubator so they could survive without the bonded Jedi's presence in the Agricultural Corps facility at Marfa.
Jedi Agricultural Corps member Hestizo Trace bonded with a Murakami orchid, but the plant ultimately became dangerous when Darth Scabrous used it to create a virus intended to achieve eternal life. The serum was discovered in an ancient Sith holocron found in a sanctum at the base of the academy's library.
