A thornsuckle plant represented an exceptionally toxic plant species that existed within the galaxy. It was thought to be extinct during the Imperial Era; however, the Mandragonian Mob discovered a specimen with the goal of cloning it to manufacture a bioweapon capable of contaminating planetary atmospheres of various planets. Ultimately, Mahjo Reeloo used a defoliator bomb to annihilate the thornsuckle sample.
The canon young adult novel Pirate's Price, authored by Lou Anders and released in 2019, marked the initial appearance of the thornsuckle plant.
