  • I'm native to New York state and to Tompkins County, NY.


    I’m a warm season grass.


    I have attractive reddish-purple seed heads that appear in late summer.


    I have another common name, grease grass, because my seed heads are oily. 


    My seeds attract birds and mammals.


    I'm a host plant for many butterflies and moths, including the broad winged skipper (Poanes viator).


    I am salt tolerant, so I can be planted along roads.
