Lupinus rivularis

Our plant was gifted to us by Kenton Seth of crevice garden fame who also happens to be a keen plantsman. This is native to the coastal areas of the West coast where it is found in moist meadows and along streams where it can naturalize in gravel bars. Blue and white flowers are awesome for pollinators. It will tire out after a few short years but save seed or let it naturalize via self-sowing.
