Big bluestem is the signature grass of the tallgrass prairie. It can grow 6-8 feet tall. The flower spkelets are arranged in a few narrow spikes that are clusted at the tops of the stems, lookimg like a bird’s foot, and giving this specis the charming alternative name “turkey-foot.”
Grasses are wind-pollinated, and thus lack coloerful petaslsd and sepals. The flowers consisist of large dangling stamens that release copious amounts of pollen inot the air, and pollen-receptive stimas that are plumose, thus able to capture the wind-borne pollen. The photo below show both the anthers and the stigmas.
