Big Bluestem Grass, also known as Andropogon gerardii, is a warm-season, perennial grass native to North America. It is an important component of the tallgrass prairie ecosystem, which is characterized by its rich biodiversity and high levels of productivity.

Pollination of Big Bluestem Grass is primarily achieved through wind dispersal, as the grass produces large amounts of pollen that are easily carried by the wind. However, it is also visited by a variety of insects, including bees, butterflies, and moths, which can help to increase its seed production.

Insects are attracted to the flowers of Big Bluestem Grass, which are arranged in clusters called spikelets. Each spikelet contains multiple flowers, which are surrounded by bristles that help to protect them from grazing animals. The flowers are relatively small and inconspicuous, with six stamens and two stigmas.

As the flowers mature, they produce large amounts of pollen, which is released into the air and carried away by the wind. However, some of the pollen may also be picked up by pollinating insects, which can then transfer it to other flowers as they move from plant to plant.

Overall, while wind dispersal is the primary mode of pollination for Big Bluestem Grass, insects can also play an important role in helping to increase its seed production and overall reproductive success.

Planting and Care for Big Bluestem Grass (Andropogon gerardii)

Big Bluestem Grass, also known as Turkeyfoot, is a tall and hardy native grass that can reach up to 8 feet tall. It is drought-tolerant and can be used for both ornamental and ecological purposes. Here are some tips for planting and caring for Big Bluestem Grass:

Planting

• Choose a location with full sun and well-draining soil. Big Bluestem can tolerate a wide range of soil types, but prefers sandy or loamy soil.
• Sow seeds in the spring after the danger of frost has passed. Seeds should be planted at a depth of 1/4 to 1/2 inch.
• Water the area lightly after planting. Keep the soil damp until the seeds have germinated.
• Space plants 24 to 36 inches apart.

Care

• Water the grass regularly during the first year of growth. After that, Big Bluestem is drought-tolerant and will only need supplemental watering during prolonged dry spells.
• Do not fertilize Big Bluestem. It can thrive without added nutrients and excessive fertilization can cause it to flop over.
• Mow the grass to a height of 3 inches in the late fall or early spring. This will help promote new growth.
• Big Bluestem is a warm-season grass and will go dormant in the winter. Leave the dead foliage on the plant to provide winter interest and important habitat for birds and insects.

With proper planting and care, Big Bluestem Grass can be a stunning addition to any landscape. Its feathery seed heads and gorgeous fall color make it a standout plant in a meadow or native planting. Additionally, it is an important food source and habitat for birds and other wildlife.
