Jandarra was a small, tubular, purple and green vegetable native to Jubilar. Considered a delicacy, the plant would usually only grow after rare rainstorms in the desert which made it hard to cultivate. It was also one of Leia Organa Solo's favorite treats.
Shalam imported it but at a 100% tariff, bringing its worth there down by half the cost, thereby forcing the people of Jubilar to smuggle jandarra to the planet for processing.
