Poa arachnifera, the Texas bluegrass, is a species of grass. It is a dioecious perennial plant, native to the southern Great Plains of the United States.[1]
During the 1990s, botanists began experimenting with producing hybrids of Texas bluegrass and Kentucky bluegrass (Poa pratensis) for use as wintering foraging plant for grazing livestock and as a drought-resistant lawn grass. The hybrids appear similar to Kentucky bluegrass, but maintain their green color in higher temperatures.[2] Seed manufacturers began marketing the first of these hybrids, often termed "heat-tolerant bluegrasses", in the first decade of the 21st century.
