Vektroid’s alias for Floral Shoppe was Macintosh Plus, named after the computer of the same name. The album is frequently cited as an example of the then-emerging Internet-based vaporwave subgenre, along with works from other artists released by the record label Beer on the Rug. Prior to Floral Shoppe, she had previously produced other chillwave and vaporwave releases under multiple pseudonyms, including Vektroid, Laserdisc Visions, dstnt, and New Dreams Ltd. Adam Harper of Dummy, in an article about the vaporwave culture, described the album’s content as “chopped, glitching and screwed adult contemporary soul alongside twinkling spa promotional tunes.”

Xavier’s production on the album is characterized by her use of looped and time-stretched samples of adult contemporary soul music, and its overall stylistic quality has been described as “chopped and screwed meets AOR, synth funk, contemporary R&B and new-age”. Xavier takes a rather unsettling approach to sampling throughout Floral Shoppe, with “voices slowed to wordless drawls, tempos abused at whim, [and] snippets mashed over each other at clashing time signatures.” Material sampled throughout the album includes several songs from new-age group Dancing Fantasy’s 1993 studio album Worldwide, various funk and R&B songs from the 1980s, and the soundtrack for the 1997 video game Turok: Dinosaur Hunter.
