Gentiana decumbens, commonly known as Gentian, is a perennial herb native to alpine and subalpine meadows and slopes of Eastern Asia, particularly in China and Japan. This plant exhibits a moderate growth rate and typically reaches a height and width of 0.5-1.5 feet (0.15-0.5 meters). Gentian features striking, deep blue flowers that are quite showy and bloom in the summer, adding a splash of color to the garden. The lance-shaped leaves are arranged in a decussate fashion, and the plant forms a low mound that can be quite dense.

Gentiana decumbens is valued for its vibrant blue flowers and its ability to thrive in cooler climates, making it a popular choice for rock gardens, alpine collections, and as a border plant in temperate regions. It requires consistent moisture but is relatively low-maintenance once established. It prefers full sun to part shade and grows best in well-drained, neutral to slightly acidic loam soils. While generally pest-free, it can be susceptible to root rot if overwatered or planted in poorly draining soils.CC BY-SA 4.0
