It is native to the northwestern United States from northern California to Idaho to Washington, its distribution extending north into British Columbia. Its habitat includes meadows and streambanks. It is an annual herb approaching half a meter in maximum height, its aromatic herbage coated in glandular and nonglandular hairs. The elongated or lance-shaped leaves are 2 to 4 centimeters long.
