Zoom To My AddressZoom To California Estimated Plant Range

About Silver Lupine (Lupinus albifrons) Silver lupine, white-leaf bush lupine, or evergreen lupine, is a perennial species native to California, Oregon, and northern Baja. It grows along the coast, foothills of the Sierras and into the mountains, in dry and open meadows, prairies and forest clearings. It is a member of several plant communities, including coastal sage scrub, chaparral, northern coastal scrub, foothill woodland, and yellow pine forest. It is a perennial shrub, taking up about 2 feet of space and reaching 5 feet. It has a light blue to violet flower on 3-12 inch (7.6-30 centimeter) stalks. The leaves are silver with a feathery texture. There are four recognized varieties in California that are found in different parts of the state and having some differences in habit and requirements.

It prefers full sun with good drainage and likes sandy or rocky soils that are dry, but will tolerate some moisture. If conditions are right it will be long-lived.
