Osha

Ligusticum porteri, also known as osha (pronounced OH-shuh) or Porter lovage, is a perennial herb found in parts of the Rocky Mountains and northern New Mexico, in the southwestern United States.

Osha is strictly a mountain plant, and it is most commonly found in deep, moist soils rich in organic material. The plant requires partial shade. Osha is widely distributed in the Rocky Mountains and the high mountains of northwestern New Mexico. It is most common in the upper limits of the subalpine zone, so in the southern part of its range, it grows at elevations from 7,000 feet to 10,000 feet (2100 m to 3000 m), while in Utah and Wyoming, it grows as low as 5,000 feet (1500 m).
