The bubse tree was a bulb-shaped tree that was native to the Outer Rim world of Saleucami. Because of their use as specialized medicinal exports for the discriminating Zealots of Psusan religious group, plant root pieces and mineral water gathered from the bubse tree commanded substantial prices.
Within established Star Wars canon, the bubse tree was initially referenced in the article "Visiting Saleucami." This article appeared in the "Guide to the Galaxy" section of Star Wars: Build the Millennium Falcon 44, a publication by De Agostini released around November 4, 2015. The trees began in the Star Wars Legends timeline; their initial mention came in The Essential Atlas, a 2009 reference book authored by Jason Fry and Daniel Wallace.
