Our Glorious Grasses ~ Bushy Bluestem

One of our most dramatic fall grasses, bushy bluestem (Andropogon glomeratus) thrives across the southern half of Texas. Unlike other species in the bluestem genus, A. glomeratus prefers sunny, moist locations; it often decorates ditches or fills low, damp fields with its unmistakable foliage.

During the growing season, the grass develops in pretty green bunches, sometimes tinged with tones of blue or copper. In autumn, its feathery plumes emerge — sometimes quickly and dramatically — showing why the grass also is known as ‘beardgrass.’ Eventually, it takes on an attractive rusty color that endures throughout the winter.

Like other bluestems, the grass is beneficial to a wide variety of wildlife, giving food, shelter, and nesting material to small mammals, insects, and birds.

Despite its bunched-up appearance and growth habits that sometimes make details hard to discern, its feathery seeds are extraordinarily pretty, especially when seen against a blue sky and still-green foliage.

A Very Bushy Bluestem

While frost forms in the American midwest and trees take on dramatic colors in the northeast, changes in Texas grasses mark the season’s turning along the coastal plain.

One of our most dramatic grasses,  bushy bluestem (Andropogon glomeratus) grows both tall and full, its blue-green summer foliage becoming a rich, coppery brown as autumn ripens. Rooted in the Greek words for ‘man’ and ‘beard,’  both the genus name, as well as the less-favored common name of bushy beardgrass, refers to the long, soft hairs of its seed heads.

Native to the southeastern United States, parts of central Mexico, and the Caribbean, the plant can be found as far north as New England. Unlike other members of Andropogon, it thrives in moist soil, preferring areas such as roadside ditches, swamp margins, seasonal ponds, wet pastures, and river banks.

Generally, the full beauty of the grass emerges gradually, until its changed color and sunlit tufts of fluff dominate the surrounding landscape. But at least one plant at the Brazoria Wildlife Refuge couldn’t wait, exploding into full autumn glory ahead of its companions.
