Information on Anderson Lupine


Anderson's lupine, or Lupinus andersonii, is a species of lupine native to California and parts of southern Oregon. This herbaceous perennial is also found in the remote mountain areas of Nevada. There are hundreds of species of lupine, according to Washington State University. Anderson's lupine is much like many other species of lupine in both appearance and growing conditions.


Anderson's lupine grows in dry, mountainous regions with altitudes of 4,000 to 8,500 feet above sea level, according to the Calflora website. The wildflower clings to the slopes and ridges of these mountains. Anderson's lupine is also commonly found growing along the hiking trails in the Yellow Pine Forest, Lodgepole Forest and Red Fir Forest in California.


Lupinus andersonii has foliage and stems that are covered with fine hairs, giving the plant a fuzzy appearance. The plant averages between 2 and 3 feet in height and features tall stalks covered with small purple, creamy-yellow or white flowers. The pale green leaves are composed of six to nine long, slender leaf sections joined in the middle and arranged in a circle.


Lupines in general are hardy plants, and Lupinus andersonii is not an exception. This species thrives in dry, mountain soil. Anderson's lupine can adjust to many soil types, according to Washington State University, except very wet soil. These plants thrive in full sun or partial shade and do not need fertilizing. Lupines create their own nitrogen and increase the fertility of the soil they are planted in.


Many types of lupines are poisonous to animals, according to Washington State University. Livestock may try to graze on Anderson's lupine, and this can have devastating results. The seeds are especially toxic and can cause vomiting and convulsions, especially in smaller animals such as sheep or household pets.


Many lupine are grown in home gardens or landscapes. They make excellent border plants and are especially attractive when planted in groups. Anderson's lupine is a terrific choice for coarse, rocky areas of a home garden that are exposed to full sunlight. It is so hardy that it will grow in adverse conditions where other plants may wilt.
