Lupinus bicolor

Dwarf Lupine or Pacific Lupine is a widespread small hardy annual that is found all along the west coast from British Columbia to Mexico. In the Willamette Valley its most conspicuous home is along the disturbed soil and gravel of highways/roads. Thats where you see masses of this diminutive lupine that rises to just 1′ tall. The intricate flowers erupt from the top and are mostly blue with purple and the bottom has a white lip. These are displayed above very furry palmate leaves. It forms a small rounded plant. Loved by all pollinators this tough little plant can inhabit the worst, shallow soils and still thrive. If given richer conditions this nitrogen fixer will soar to 1′ tall with a much larger flowers. Excellent in annual containers – it blooms for a long time April-August or until the ground goes completely dry. Horizontal bean pods hold three seeds each. Self sows in open disturbed sites with little competition from other plants. Only water if it is planted from a container otherwise no supplemental irrigation necessary. Very beloved by hummingbirds and butterflies.  Mixes well with other long blooming hardy native annuals such as Madia elegans or Clarkia amoena. Seed that is released in summer germinates in autumn with the first fall rains. Easy to spot the palmate leaves. Oregon native plant.
