Halenia deflexa, also known as green gentian or spurred gentian[1][2] is a native flower of the northern regions of the United States (Montana, North Dakota, Wisconsin, Michigan, Maine, and Pennsylvania) as well as all of Canada.

Each has a spur up to a fifth inch long, extending back past the sepals (each of the parts of the calyx of a flower, enclosing the petals).

The color of H. deflexa is a shade of purple or a light green.

The fruit of the plant is a capsule, conical in shape, which sticks out from the opening of the flower.

[3] The green gentian has simple leaves that are small, typically measured at 1 to 5 cm (1⁄2 to 2 in) long and 5 to 20 mm (1⁄4 to 3⁄4 in) wide.
