Trumpet gentian is a stunning alpine perennial that thrives in cool, moist climates with humus-rich, well-drained soil and plenty of bright light. It requires careful attention to soil pH (slightly acidic) and resents hot, humid summers, making it best suited for rock gardens or alpine beds. Consistent moisture and good drainage are essential — this plant will struggle in heavy clay or drought conditions.
