AUSTRALIAN BLUESTEM Meaning and
Definition
-
Australian bluestem refers to a warm-season perennial grass species native to Australia, scientifically known as Bothriochloa pertusa. Also commonly known as redgrass or tanglehead, Australian bluestem belongs to the Poaceae family and is widely recognized for its agricultural and ecological importance.
Characterized by its long and slender leaf blades, Australian bluestem typically forms dense clumps or tufts that can reach heights between one to three feet. Its clumping habit and aggressive growth make it an excellent choice for soil stabilization, erosion control, and forage production. The grass is also known for its adaptability to a range of soil conditions and climates, including both drought-prone and flood-prone areas.
In terms of appearance, Australian bluestem features erect flowering stems with dense, bushy seed heads that usually take on a reddish or purplish coloration. These seeds, known for their sharp and woody nature, tend to easily detach from the plant and can be a concern for livestock, causing injuries and undesirable seed dispersal. Nonetheless, in certain regions, Australian bluestem is utilized for pasture as a drought-tolerant forage grass due to its palatability and nutritional value.
Given its versatility and adaptability, Australian bluestem has been introduced to various regions around the globe, including parts of the United States, where it has gained both popularity and concern as an invasive species. Its aggressive growth and ability to outcompete native grasses in certain habitats have led to the need for careful management and monitoring to prevent ecological disruptions.
