Marram grass forms a culm that remains short (~2") if no inflorescence is produced but reaches heights of 30" with an inflorescence. Culms produce a 6-12" long spike-like panicles of single-flowered spikelets each 9-15 mm long. Flowers are wind-pollinated, as is common in grasses. This plant is endangered in Illinois and is restricted to beaches along the Lake Michigan shoreline where it is often the dominant grass.
