Gentianopsis crinita (sometimes called greater fringed gentian or blue gentian) is a biennial herbaceous species, native to eastern USA and eastern Canada.

[2] It grows in moist, limey woods, meadows, and stream banks.

[3] In autumn, solitary, iridescent blue flowers develop on naked peduncles approximately 2 to 10 cm (3⁄4 to 4 in) in height.

The outermost flower parts are two pairs of green sepals, strongly winged and flared on the basal margins, the outer pair much larger than the inner.

[4] According to ancient Roman naturalist Pliny, King Gentius of Illyria found that the roots were useful as an emetic, cathartic, and tonic.
