Panicum spretum of Michigan Flora.

Sandy, mucky shores, especially during low water years, sandy wet meadows and swales, sometimes bog margins; in acidic soils.

A species primarily of the Atlantic Coastal Plain, disjunct into Michigan but more widespread than some Coastal Plain disjuncts. This is a taller and more slender plant than its relatives, rarely to nearly 1.5 m tall, and robust material is quite distinctive with its narrow vernal panicles, up to 12 cm long and 4 times as long as wide densely populated with short-peduncled spikelets. Shaded, lax plants, plants with only autumnal panicles, and depauperate specimens are more difficult to determine. Sometimes subsumed under a broadly circumscribed D. acuminatum as subsp. spretum (Schult.) Freckmann & Lelong.
