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[citation needed] 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.
