GENUS SUMMARY: A genus of about 300-325 species, nearly cosmopolitan (most diverse in tropical and subtropical regions, and especially South America). This technical genus is known well by only a few botanists, and additional undescribed taxa are possible.
GENUS IDENTIFICATION: Identification notes: In vegetative condition, Xyris is often confused with other monocots with equitant leaves, such as Iris spp. (Iridaceae), Lachnanthes caroliniana (Haemodoraceae), and Tofieldia spp. (Tofieldiaceae).

Plant Sale Text: Giant yellow-eyed grass is not a grass at all, but it has skinny flat leaves like a grass and cool twisted stems. The 3-petaled yellow flowers are interesting and unusual, as they are arranged at the top of a cylindrical spike on a tall stem. Native to wet flatwoods, depression ponds, and sandhill seepage slopes of the Coastal Plain of the southeastern United States, giant yellow-eyed grass is a good choice for bog gardens or other sunny soggy areas of the garden.
