This article contains plot details from the latest book.
Vesperlace is a plant, mentioned in Flashback, that is showcased by Flori in her endeavor to create a song that would get rid of Sophie and Fitz's echoes. In the daytime, it appears as a wispy vine with leaves of a darker shade that has small clusters of pearl white buds. It is said to only bloom at night, though its night-form was not shown. It only is able to grow in the darkest points of the most silent forests. According to Flori, its melody is like the rhythm of darkness, that is the same pulse as that of the echoes. It may connect to Vespera, as it has "Vesper" and has the rhythm of darkness.
