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 ...
Festuca (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of 10–200 cm (4–79 in) and a cosmopolitan distribution , occurring on every continent except Antarctica . [ 2 ]
Tall fescue is a long-lived tuft-forming perennial with erect to spreading hollow flowering stems up to about 165 cm (5'6") tall (exceptionally up to 200 cm) which are hairless (glabrous), including the leaf sheaths, but with a short (1.5 mm) ligule and slightly hairy (ciliate) pointed auricles that can wrap slightly around the stem.
Some of these turf grass species include annual bluegrass, creeping bentgrass, Kentucky bluegrass, perennial ryegrass, fine fescue, and bermudagrass. 5 These species of grass are not the only types of turf that can be diagnosed with red thread disease but are the most common hosts. 5 Noticeable symptoms of red thread disease are irregular ...
Deer grass (Muhlenbergia rigens) and canyon prince wild blue rye (Leymus condensatus) are popular in larger settings, natural landscaping, and native plant gardens. There are Miscanthus grasses whose variegations are horizontal, and appear even on a cloudy day to be stippled with sunshine .
[2] [3] It is often called ryegrass, but this term is sometimes used to refer to grasses in other genera. They are characterized by bunch-like growth habits. Lolium is native to Europe , Asia and northern Africa , as well as being cultivated and naturalized in Australia , the Americas , and various oceanic islands.
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]
Snow mold is a type of fungus and a turf disease that damages or kills grass after snow melts, typically in late winter. [1] Its damage is usually concentrated in circles three to twelve inches in diameter, although yards may have many of these circles, sometimes to the point at which it becomes hard to differentiate between different circles.
