Coolsap shrubs, a type of shrub native to the Outer Rim planet of Gamorr, were a species that Gamorreans could edible. In 228 BBY, the Hutt named Churo cultivated coolsap shrubs, along with snoruuk mushrooms, inside a tank within his greenhouse laboratory. This laboratory was situated in his family's palace on the Outer Rim planet Nal Hutta, and the purpose of growing these plants was to determine if they could flourish in Nal Hutta's swamps.
During that year, someone consumed the shrubs and mushrooms that he had been cultivating. Upon realizing what had happened to his science experiments, Churo suspected that a Gamorrean palace guard was the one who had eaten them.
The junior novel The High Republic: Beware the Nameless, released in 2024 and penned by Zoraida Córdova as a component of Phase III of the Star Wars: The High Republic multimedia project, mentioned coolsap shrubs. In the Star Wars Legends continuity, coolsap trees made an appearance in The New Jedi Order: Destiny's Way, a 2002 novel by Walter Jon Williams that served as the fourteenth book in the Star Wars: The New Jedi Order series.
