arroyo lupine
One of the easier-to-grow lupines, this long-blooming ANNUAL is low maintenance and thrives in heavier soils. Bright-green, palmate leaves topped by purple-blue spires quickly reach 2-3 feet tall and wide—or more, if happy. Reseeds easily and returns with winter rains, or whenever conditions are moist and fertile. Although it enjoys moderate to occasional water, it will tolerate both wet and dry areas. Arroyo lupine is found in diverse habitats with a broad native range in California, but prefers full sun and clay-rich soil. Looks splendid planted en masse and can serve as a nitrogen-fixing, seasonal groundcover. All parts of the plant are toxic if eaten, but it is a great nectar plant for bees and butterflies. Deer resistant.
