Since the 1950s and early 1960s, 90% of Kentucky bluegrass seed in the United States has been produced on specialist farms in Idaho, Oregon and Washington. During the 1990s [citation needed] botanists began experimenting with hybrids of Poa pratensis and Texas bluegrass (P. arachnifera), with the goal of creating a drought and heat-resistant ...
Before European-American settlement, various cultures of Indigenous peoples of the Americas lived in the region. The pre-colonization state of the Bluegrass is poorly known, but it is thought to have been a type of savannah known as oak savanna, with open grassland containing clover, giant river cane (a type of bamboo), and scattered enormous trees, primarily bur oak, blue ash, Shumard's oak ...
Marram grass, Ammophila arenaria specialises in this, and is largely responsible for the formation and stabilisation of many dunes by binding sand grains together. The sand couch-grass Elytrigia juncea also performs this function on the seaward edge of the dunes, and is responsible, with some other pioneers like the sea rocket Cakile maritima ...
These species, commonly called zoysia or zoysiagrass, are found in coastal areas or grasslands. [5] It is a popular choice for fairways and teeing areas at golf courses. The genus is named after the Slovenian botanist Karl von Zois (1756–1799).
In Florida, sandhills receive 130 cm (51 in) of rainfall per year, just like the more hydric ecosystems surrounding them. Sandhills are xeric because they have poor water holding capacity. Dominant vegetation includes longleaf pine (Pinus palustris), American turkey oak (Quercus laevis), and wiregrass (Aristida stricta). [1]
Poa secunda (variously known by the common names of Sandberg bluegrass, [2] [3] [4] alkali bluegrass, [4] big bluegrass, [4] Canby's bluegrass, [2] Nevada bluegrass, [4] one-sided bluegrass, [3] Pacific bluegrass, [2] pine bluegrass, [2] slender bluegrass, [2] wild bluegrass, [4] and curly bluegrass [1]) is a widespread species of perennial bunchgrass native to North and South America.

Forests are dominated by a mixture of needle-leaved and broad-leaved evergreen trees, including sand pine (Pinus clausa), slash pine (Pinus elliottii), longleaf pine (Pinus palustris), southern live oak (Quercus virginiana), cabbage palm (Sabal palmetto), pignut hickory (Carya glabra), and sand hickory (Carya pallida).
The Algodones Dunes is a large sand dune field, or erg, located in the southeastern portion of the U.S. state of California, near the border with Arizona and the Mexican state of Baja California. The field is approximately 45 miles (72 km) long by 6 miles (9.7 km) wide and extends along a northwest-southeast line that correlates to the ...
