Stiff gentian is a beautiful wildflower also known as Gentiana erecta. It grows in mountainous regions and blooms in late summer and early fall. Though it's commonly known as stiff gentian, there are several other synonyms for the flower, including: closed gentian, bottle gentian, trumpet gentian, and blind gentian. Each of these synonyms refers to a different aspect of the flower's appearance or behavior. For example, the closed gentian name comes from how the flower's rounded petals remain closed unless a bee or butterfly pushes its way in. Meanwhile, the name bottle gentian comes from the shape of the flower, which resembles a bottle with a narrow neck. Regardless of the name used, this wildflower is a stunning addition to any natural landscape.
