Summary
Gentiana clausa, commonly known as Closed Gentian, is a perennial herb that typically grows 1–2 feet tall and is native to moist meadows, wetlands, and woodlands at higher elevations throughout Eastern North America, extending from Quebec through the Appalachian Mountains to North Carolina and Tennessee. This species is characterized by its upright, unbranched stalks and paired, lanceolate leaves. The striking feature of Closed Gentian is its blue, tubular flowers that remain closed or nearly so, blooming from late August to October. The flowers’ unique appearance adds an element of intrigue to the garden during the fall season.
Closed Gentian is valued for its late-season blooms and adaptability to various garden settings. It is often used in wildflower gardens, borders, and naturalized areas, where it provides a splash of color when many other plants have finished flowering. While it can tolerate full sun, it prefers part shade conditions, especially in hot climates. Closed Gentian requires medium amounts of water and thrives in soils with good drainage. It is not commonly afflicted by diseases or pests, making it a low-maintenance addition to the garden. However, it can be sensitive to overwatering and poor drainage.CC BY-SA 4.0
