Nightbloomer

"There isn't much vegetation here&mdash;a few spinebarrels in the shadows and maybe a nightbloomer where a bit of dirt's piled up in cracks in the rocks."

- Rey describes the vegetation of the Goazon Badlands in her survival guide

Nightbloomers were a type of vegetation which could occasionally be found in the Goazon Badlands region of the desert planet Jakku. They produced rind and flowers known as nightblossoms Alongside spinebarrels, they were one of the only plants that could survive in the area, and would only be found growing out of dirt that had gathered in cracked rocks. Members of the Teedo species brought supplies including nightbloomer rind, spinebarrel flesh and water to the individual known as the Sitter while he sat atop his pillar in the Badlands, which allowed him to survive. The scavenger Rey collected nightblossoms and other flowers to display in her home in order to remind herself that there was beauty even on Jakku as long as you looked hard enough. She wrote about the plants in a survival guide she compiled around thirty years after the Battle of Endor.

Behind the scenes
Nightbloomers were first mentioned in the replica journal Star Wars: Rey's Survival Guide, which was written by Jason Fry and released in 2015 in conjunction with the film Star Wars: Episode VII The Force Awakens. While both the film and book also depict some of the flowers Rey keeps in her home, no source has yet made clear if any of these are meant to be nightbloomers.
