Lupinus citrinus is a species of lupine known by the common names orange lupine, orangeflower lupine, and fragrant lupine. It is endemic to California, where it is known from a section of the Sierra Nevada foothills extending from Mariposa to Fresno Counties.[1] This is an annual herb growing 10 to 60 centimeters tall. Each palmate leaf is made up of 6 to 9 leaflets up to 3.5 centimeters long. The herbage is coated in tiny white hairs. The inflorescence bears several flowers, sometimes in whorls. Each flower is roughly a centimeter long and orange to yellow to white in color. The fruit is a legume pod 1 or 2 centimeters long containing seeds which resemble "pieces of granite."[2]
