Silvery Lupine
Lupinus argenteus
In the United States:
Native
· also called silver-stem lupine, spreading lupine
Silvery lupine serves as a pollen source for honeybees, supporting brood rearing during its midsummer bloom period from June to August, though it produces little nectar. The blue-violet flower spikes emerge on silvery-haired stems, drawing foragers to sunny, dry sites. It prefers well-drained soils and may need staking in windy areas to prevent lodging.
