Gentiana saponaria (soapwort gentian or harvestbells) is a 1–2 ft (30–61 cm) tall flowering plant in the Gentianaceae family. It is native to eastern North America south of the Great Lakes, from Wisconsin to New York, and south to Texas and Florida. Similar to the "Bottle Gentians" like Gentiana clausa and Gentiana andrewsii, it has paired, lanceolate leaves on unbranched stalks, blue or purple blooms, and a stout taproot. It is rare in its range, usually found in undisturbed sandy soils. The flowers are pollinated by bumblebees.
