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 ...
During the purplish blue phase the seed stems have a dark blue coating. "Bluegrass" is a common name given in the United States for grass of the Poa genus, the most famous being the Kentucky bluegrass. [2] Despite its name, Kentucky bluegrass is native to Europe and was likely introduced around 1600. [3] [4]
Bluegrass, which has green leaves, derives its name from the seed heads, which are blue when the plant is allowed to grow to its natural height of two to three feet (0.6 to 0.9 meters).

With its low-growing form and delicate foliage, lawn burweed is a stealthy weed you may not even notice. That is, until you step on its tiny, sharp seeds, or burs. “When these are present, it ...
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 ...
Poa annua, or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. [2] This grass originated as a hybrid between Poa supina and Poa infirma. [3]
Kentucky is an agricultural producer in the United States. Value of agricultural products was $5 billion in 2012, of which slightly less than half was crops. [1] Crops grown in the state include corn, soybeans, hay, wheat and tobacco. [2] Historically, hemp has been a cash crop in the state (see hemp in Kentucky).
