Panic grass

Panic Grass is a common name for several species of grasses in the genus Panicum, which is part of the family Poaceae. The genus is widespread across many habitats and continents, and is particularly prevalent in tropical and subtropical regions.

Description

Panic grasses are typically perennial, though some species are annual. They are characterized by their flat, linear leaves and their panicle inflorescences, which give the genus its common name. The seeds of panic grasses are small and hard, and are often an important food source for birds and small mammals.

Species

There are over 400 species of panic grass worldwide. Some of the most well-known include:

• Panicum virgatum, or switchgrass, is a tall prairie grass native to North America. It is used for forage and is also an important species for biofuel production.
• Panicum capillare, or witchgrass, is a common weed in many parts of the world.
• Panicum miliaceum, or proso millet, is a domesticated species grown for its grain in many parts of the world.

Ecology

Panic grasses are found in a wide variety of habitats, from wetlands to deserts. They are often an important component of grassland ecosystems, and can also be found in disturbed areas such as roadsides and agricultural fields. Some species are adapted to fire and can quickly recolonize burned areas.

Uses

Many species of panic grass are used by humans. Some, like proso millet, are grown for their grain, while others are used for forage for livestock. Some species are also used in landscaping for their ornamental value.
