About Lupinus citrinus Kellogg
Lupinus citrinus Kellogg is a species of lupine with the common names orange lupine, orangeflower lupine, and fragrant lupine. It is endemic to California, occurring only in a stretch of the Sierra Nevada foothills that runs from Mariposa County to Fresno County. This plant is an annual herb that grows between 10 and 60 centimetres (3.9–23.6 inches) tall. Each of its leaves is palmate, made up of 6 to 9 leaflets that can reach up to 3.5 centimetres (1.4 inches) long. The leafy and stem tissue of the plant is covered in tiny white hairs. Its inflorescence holds several flowers, which sometimes grow in whorls. Each flower is approximately one centimeter long, and its color ranges from orange to yellow to white. The plant produces a fruit that is a legume pod 1 to 2 centimetres (0.79 inches) long, containing seeds that look like "pieces of granite."
