Clustered green gentian is a monocarpic perennial herb of the gentian family, native to meadows and woodlands in the northwestern US, that grows up to about 1.5 m tall and flowers once before dying. It needs open, well-drained sites and patience, since it may take several years to bloom.
Frasera fastigiata (syn. Swertia fastigiata) is a species of flowering plant in the gentian family known by the common name clustered green gentian. It is native to the northwestern United States, where it grows in meadows, grasslands, woodlands, and forest openings. It is a perennial herb that grows 5 ft (1.5 m) tall. The basal leaves have oval or spoon-shaped blades up to 30 centimeters long by 10 wide. Leaves higher on the stem may be smaller and narrower. Some of the leaves have white margins.
