Big Bluestem and Little Bluestem are both native grasses commonly found in the United States. While they share a similar name, there are some notable differences between the two.
1. Size and Growth Habits:
Big Bluestem (Andropogon gerardii) is a tall, warm-season grass that can reach heights of up to 6-8 feet. It grows in large clumps and has a distinct three-parted seed head. On the other hand, Little Bluestem (Schizachyrium scoparium) is a smaller grass, typically growing to a height of 2-4 feet. It forms tight bunches and has a more delicate seed head.
2. Palatability:
Big Bluestem is generally more palatable to grazing animals compared to Little Bluestem. The leaves of Big Bluestem are wider and have a higher nutritional value, making it a preferred forage option for livestock. Little Bluestem, although less palatable, is still grazed by some animals, especially during periods of scarcity when other forage options are limited.
3. Drought Resistance:
Little Bluestem is known for its exceptional drought resistance. Its dense root system enables it to access water deep within the soil, making it well-suited for arid conditions. Big Bluestem, while still moderately drought-tolerant, may require more water to thrive compared to its smaller counterpart.
4. Ecological Importance:
Both grasses play important ecological roles. Big Bluestem is a dominant component of tallgrass prairies and provides habitat and food sources for various wildlife species. It also helps in preventing soil erosion. Little Bluestem, on the other hand, is often found in mixed-grass prairies and is an important component of grassland ecosystems. It provides nesting sites and cover for birds and small mammals.
5. Aesthetics and Landscaping:
Big Bluestem, with its towering height and attractive seed heads, can create a dramatic visual impact in the landscape. It is commonly used in prairie restoration projects or as an ornamental grass in larger gardens. Little Bluestem, with its compact form and beautiful reddish-brown fall color, adds a touch of elegance to any landscape. It is often used in meadow plantings, borders, or as a low-maintenance ground cover.
While both Big Bluestem and Little Bluestem are native grasses with similar names, they differ in terms of size, palatability, drought resistance, ecological importance, and landscaping potential. Understanding these differences can help gardeners and landscapers choose the most suitable grass for their specific needs and environmental conditions.
