Hai-ka blossoms were a species of flower utilized in burial customs on the Outer Rim world of Akiva. These blossoms bore a resemblance to the plumage of a firebird, sharing both its gentle texture and vibrant hue. In the year 5 ABY, wreaths crafted from these blossoms were presented at the memorial service for Akivan citizen Brentin Lore Wexley, with his offspring, Temmin Wexley a New Republic agent, among the recipients.
By the era of the Galactic Empire on Akiva, the practice of crafting garlands from these blossoms had become a customary part of Akivan funeral rites. While visiting the residence of his former lover on Chandrila, a Core Worlds planet, in 5 ABY, Sinjir Rath Velus, a former Imperial compliance officer, observed the lack of decorative elements, musing on his own preference for vibrant accents such as a hai-ka flower bouquet or a cerulean octo-fish container. Shortly thereafter, hai-ka flower garlands were prepared for the ceremony honoring Brentin Lore Wexley on Akiva, with some being given to the deceased's son, Temmin Wexley, who served as an operative for the New Republic. During the funeral procession, Temmin contemplated the flowers' physical attributes and their resemblance to the plumes of a firebird.
During the New Republic Era, Kiza, an operative of the Sith Eternal, was amassing an army of combat droids within her personal flagship, acting under the influence of the dark side of the Force due to her wearing of the mask belonging to the Sith Lord Exim Panshard. In 21 ABY, Kiza initiated the preparation of several seeker droids for deployment by activating a furnace, noting that the furnace's slotted shielding opened in a manner similar to the blossoming of a hai-ka flower.
Hai-ka flowers were initially introduced in Aftermath: Empire's End, a 2017 novel authored by Chuck Wendig and serving as the concluding volume in the Star Wars: The Aftermath Trilogy.
