Panicum flexile, commonly called wiry panicgrass,[1] is a species of flowering plant in the grass family (Poaceae).

It is primarily native to eastern to North America, where it has a scattered and localized distribution.

[2] It is typically found in mafic or calcareous open areas, both wet and dry, particularly associated with limestone.

[3][4] Panicum flexile is a rather delicate annual grass.

It can be distinguished from similar-looking Panicum by its long-acuminate spikelets arranged in a slender, elongated panicle.
